A Summer Outside: Children’s Colonies and the Nordic Tradition of Friluftsliv

There is a particular kind of photograph that appears again and again in Nordic archives from the first half of the twentieth century. A group of children stands beside a lake while others scramble over rocks, sit barefoot in the grass, eat together at long wooden tables, or crowd onto a beach. Their clothes are practical and often mismatched, if worn at all. Adults are sometimes present, but frequently somewhere at the edge of the picture. The children seem to inhabit the landscape rather than merely visit it.

There is an ordinariness to these photographs that makes them especially compelling. Nobody appears to be documenting an expedition into the wilderness. There are no carefully equipped hikers posing at the summit of a mountain. Instead, there are towels drying on railings, clothes hanging from branches, enamel cups on tables, children wandering between buildings and water, and groups sitting around on the grass. The outdoors is not the event. It is simply where life is happening.

Many of these photographs document a once enormously important Nordic institution: the children’s summer colony — barnkoloni or simply kollo in Sweden, feriekoloni in Norway and Denmark, and kesäsiirtola in Finland.

The terminology differed, as did the organizations that ran them, but the basic idea was remarkably similar. Urban children were sent away for part of the summer to live in the countryside, on islands, beside lakes, or along the coast. Sometimes the stay lasted several weeks. In earlier periods it could encompass much of the summer. Children ate, slept and lived together, usually far from their parents, under the supervision of a relatively small number of adults.

The movement was not uniquely Nordic. Children’s holiday colonies and “fresh-air” programs appeared across Europe during the late nineteenth century in response to industrialization, urban poverty and concerns about children’s health. Yet the institution found particularly fertile cultural ground in the Nordic countries. In Sweden, Norway, Denmark and Finland, generations of city children would spend part of their summers this way.

The practice was partly charitable, partly educational and partly rooted in public health. But over time it also became connected to something broader: a conviction that contact with the outdoor world was not simply entertainment for children. It was something they needed. That idea overlaps with a word that is difficult to translate neatly into English: friluftsliv.

Literally, it means something close to “open-air life” or “free-air life.” But friluftsliv does not simply mean hiking, camping or participating in outdoor sports. At its broadest, it describes a relationship with the natural world in which being outdoors is treated as an ordinary part of living. The forest, shoreline, meadow and lake are not destinations reserved for special excursions. They are extensions of everyday life.

The history of the children’s summer colony offers a particularly revealing window into how that idea came to shape Nordic childhood.

Taking the Children Out of the City

The earliest children's summer colonies emerged during the rapid urbanization of the late nineteenth century.

Cities across northern Europe were growing quickly. Industrialization drew thousands of people into urban environments whose housing and infrastructure struggled to keep pace. Working-class families could live crowded together in small apartments, often with several children sharing rooms and beds. Sanitation was poor by modern standards, industrial pollution was widespread, and infectious diseases remained an ordinary feature of urban life.

Tuberculosis in particular haunted European cities. Before antibiotics, there was no reliable cure. Fresh air, sunlight, nourishing food and removal from crowded environments became central to both medical treatment and preventative thinking. Sanatoria were built in forests, mountains and coastal areas for much the same reason.

Children occupied a special place within these concerns. A thin, frequently ill or poorly nourished child was understood as physically vulnerable to the city itself. The countryside, by contrast, increasingly represented health: clean air, sunlight, exercise, plentiful food and distance from infection. It was within this world that the children’s summer colony emerged.

The movement had roots beyond the Nordic countries. One influential early experiment was organized in Switzerland in the 1870s, and similar ideas spread through European educational, medical and philanthropic networks. They found enthusiastic adopters in the Nordic countries. Swedish holiday colonies were being organized by the 1880s. Norwegian feriekolonier developed during the same period, initially allowing working-class children from cities such as Kristiania, later Oslo, and Bergen to spend their summers in healthier rural surroundings. Denmark developed its own extensive feriekoloni tradition around the turn of the century. In Finland, municipal and private kesäsiirtolat likewise became an established part of children's summer life.

The details varied from country to country, but the underlying logic was strikingly consistent. Children were not merely going on holiday. They were being strengthened.

The Countryside as Medicine

At first, the language surrounding summer colonies could be strikingly medical. Some organizations took this principle quite literally. Stockholms Fjällkoloniförening, founded in 1899, sent particularly frail Stockholm children into the mountains. Children weakened by pneumonia, whooping cough, scarlet fever and other illnesses were thought to benefit from a summer at higher altitude. If ordinary country air was good, mountain air was considered better still.

The premise can sound quaint today. Yet behind the period's imperfect medical theories was an observation that remains recognizable: children living in crowded and unhealthy environments often did improve when given nutritious food, physical activity, sunlight, sleep and weeks away from urban pollution.

The 1930s and 1940s was an era of massive public health campaigns in the Nordic countries. Here a boy is examined by the school doctor in Uppsala, Sweden, in 1942. Paul Sandberg. Public Domain.

Across the Nordic countries, similar combinations of health, social welfare and outdoor life shaped the summer-colony movement. The countryside had become medicine.

A Cottage on Ornö

One particularly charming episode in the Swedish story began not with doctors, politicians or professional philanthropists, but with a group of schoolgirls.

In 1907, fifth-grade pupils at Kungsholmens elementarskola för flickor in Stockholm formed an association they called Små Försök — “Small Attempts.” Their ambition was wonderfully literal. They wanted to make a small attempt to help children poorer than themselves.

The girls organized a spring bazaar and raised enough money to send younger children away from Stockholm for the summer.

For that first summer, a cottage was made available on Ornö, an island in the southern Stockholm archipelago. Contemporary records associate the arrangement with the Stenbock family, whose estate encompassed large portions of the island. The children were cared for there by a local woman who already had children of her own.

The arrangement was modest. There was no enormous institution, no purpose-built complex and no elaborate educational program. A cottage in the archipelago, a woman willing to care for additional children, and enough money to make the arrangement possible were sufficient.

The following year, six children were selected from among the poorest families in Kungsholmen parish. Before leaving Stockholm they were medically examined and weighed. They then spent eight weeks in the countryside. When they returned, they were weighed again. That small detail captures the original logic of the summer colony particularly well. Success could literally be measured in kilograms.

The countryside was not merely considered beautiful or relaxing. It was expected to alter children's bodies. A successful summer meant returning home heavier, stronger and healthier than when you left.

Fresh Air — and Enough to Eat

Looking at old photographs of summer colonies, it is easy to concentrate on the picturesque elements: wooden houses, pine forests, rocky beaches and children swimming in lakes or the Baltic.

But there was another attraction that was considerably more basic. Food. For some working-class children, summer colony meant several weeks during which they could reliably eat until they were full.

Records from Små Försök describe a daily routine that included porridge and bread in the morning, a substantial midday meal, milk and sandwiches in the afternoon, and another meal in the evening. By the standards of affluent households this may not sound extraordinary. For children coming from families where food could be monotonous or insufficient, it could represent a dramatic change.

This helps explain the preoccupation with weighing children. Weight gain was visible evidence that the colony was working. The combination of food and outdoor life became almost a formula: eat, sleep, swim, run, breathe fresh air, repeat.

From the perspective of a society in which childhood obesity is often treated as the more pressing nutritional problem, it can be difficult to remember how recently adults worried about precisely the opposite. A plump child could signify health and prosperity. A thin child might signal illness, poverty or inadequate nutrition.

This aspect of the summer colonies should prevent us from romanticizing the institution too easily. They emerged partly because inequality was severe. Sending poor children into the countryside was a compassionate response to circumstances that themselves reflected profound social problems. A society in which charitable organizations had to send children away so that they could eat properly was hardly an idyllic one.

Nor should we imagine every child joyfully waving goodbye to their parents. For a young child, several weeks away from home could be an enormous separation. Homesickness was real. Some children undoubtedly loved colony life from the first day; others must have counted the days until they could return home.

Historical institutions almost always look simpler from a distance than they did to the people living inside them. Yet the popularity and longevity of the movement suggest that something larger was happening as well. The original medical and charitable justification gradually became intertwined with a broader philosophy of childhood.

A Different Geography of Childhood

At the summer colonies, much of life happened outside. Children swam. They walked. They explored shorelines and forests. They played games requiring little equipment. They picked berries, climbed, built things, helped with chores and spent long stretches of time in the company of other children.

Bad weather did not necessarily end outdoor life. Nordic outdoor culture has rarely depended upon Mediterranean sunshine. Rain meant raincoats and wet shoes. Cold water remained water to swim in. A cloudy day was still a day outside.

Children's colonies were popular  in Sweden well into the latter half of the 20th Century. Here are children at the children's colony on Värhulta island in 1967. Public Domain.

This was structured life, certainly. There were adults, schedules, meals, chores, rules and bedtimes. The romantic image of hundreds of children simply being released into the forest would be inaccurate. Yet the balance between supervision and independence was different from what many children experience today.

Adults organized the broad framework of the day, but they did not necessarily organize every minute within it. Children occupied a social world populated largely by other children. Games could continue for hours or days. Friendships and rivalries developed. Older children helped younger ones. Arguments sometimes had to be resolved without an adult immediately appearing to mediate them.

The physical environment itself encouraged independence. A child could move between the house, forest, beach and playing field without each transition becoming an organized activity. There was no need to be driven from one scheduled experience to another. Nature was not something encountered for forty-five minutes and then left behind.

It was the setting in which the day unfolded. This distinction matters. We often describe modern children as spending “time in nature,” as though nature were one activity among many: football practice on Tuesday, piano on Wednesday, nature on Saturday.

Friluftsliv suggests almost the reverse relationship.

The child is not brought into nature to perform an activity. The child is already there, and activities emerge from being there. A stick becomes a fishing rod, a sword or the wall of a shelter. A rock becomes a diving platform. A stand of trees becomes a hiding place. A path becomes an invitation to find out where it goes. None of these experiences requires much adult planning. They require something modern childhood often has in surprisingly short supply: time.

Barnens Ö

Perhaps the most famous Swedish expression of the summer-colony movement is Barnens Ö — “The Children’s Island” — on Väddö in the northern Stockholm archipelago.

The land was acquired in the early twentieth century by the Stockholm Barnens Dag organization, and generations of Stockholm children subsequently spent part of their summers there. Over time, the operation grew into a remarkable landscape of kollogårdar, cottages and communal buildings.

The scale eventually became extraordinary. By the middle decades of the twentieth century, journeys to summer colonies had become a recognizable part of Stockholm childhood. Archival photographs show crowds gathering at railway stations and docks: children carrying bags, parents standing on platforms, adults leaning through carriage windows to say goodbye.

One photograph from June 1956 captures the scale particularly well. Three hundred Stockholm children are leaving from Östra Station on the Roslagsbanan for Barnens Ö. Parents crowd the platform while children lean from the train windows. They were going away for three months. The number is striking. So is the duration.

Imagine the emotional geography of that departure. For some children it must have felt like the beginning of an enormous adventure. For others, particularly younger children, the separation must have been intimidating. For parents too, putting a child on a train knowing that much of the summer would pass before they returned required a degree of trust — in the institution, in the adults running it and, perhaps most strikingly from today's perspective, in the resilience of the child.

Today, sending a young child away for an entire summer might seem extraordinary. In 1944, it could be understood as an enormous gift: months of clean air, swimming, nourishing food, companionship and freedom from the crowded city. The departure photograph therefore captures more than an institution. It captures a different set of assumptions about what children could handle.

A Nordic Institution

Sweden provides particularly rich archival examples, but the story was unfolding across the region. Norwegian children attended feriekolonier along the coast, beside fjords and in the countryside. Danish children likewise left Copenhagen and other urban areas for colonies where fresh air, regular meals, swimming and communal outdoor life were central to the experience.

In Norway, living in harmony with nature is deeply connected to the national identity. Here Norwegian boys go for a swim in 1947. Public Domain.

Finland developed its own kesäsiirtola tradition. By the time of Finnish independence, both municipal and privately operated summer colonies were already established. After the Second World War, summer recreation for children became increasingly incorporated into public provision. In the 1960s, Finnish children from disadvantaged families or considered in need of health-promoting recreation could spend weeks or even months at a kesäsiirtola.

The Finnish experience is particularly revealing because one remnant of the old municipal tradition survives. Kessula, established by the city of Seinäjoki in 1960 beside Lake Kuorasjärvi, continues to operate summer camps for children today. The stays are now measured in days rather than months, but the activities remain strikingly recognizable: swimming, rowing, sauna, games, crafts, outdoor play and shared meals.

Across the Nordic countries, then, the precise institutional arrangements varied. So did the terminology. But the underlying idea was remarkably persistent. Take urban children away from the city. Feed them well. Give them space. Let them swim, run, explore and live outdoors.

From Necessity to Ideal

The Nordic welfare states gradually transformed the material circumstances that had given birth to the earliest colonies.

Housing improved. Childhood nutrition improved. Tuberculosis ceased to be the ever-present threat it once had been. Paid holidays expanded. Rising prosperity meant that more families could leave the city themselves. Summer cottages became accessible to broader segments of society, while cars and improved transportation made the countryside easier to reach.

The original justification for the summer colony therefore weakened. Children no longer needed to be sent away primarily because urban life was likely to leave them malnourished or physically weakened. And yet the institution did not immediately disappear. Instead, its meaning changed.

The medical language of fresh air and weight gain gradually gave way to other arguments: friendship, independence, swimming, play, confidence, community and the opportunity to experience environments unavailable in everyday city life. This transition is revealing.

If children's colonies had simply been an emergency response to urban poverty, improving living standards should have made them obsolete. Instead, Nordic societies retained them because they had come to value something about the experience itself. The means had become part of the end. Outdoor life was no longer valuable merely because it might prevent tuberculosis or put weight on a thin child. It was valuable because outdoor life had become understood as part of a good childhood.

Friluftsliv

This is where the history of the summer colony intersects with the larger Nordic relationship with outdoor life.

Friluftsliv is most directly a Scandinavian term, particularly associated with Norway and Sweden, and the histories and vocabulary of outdoor culture are not identical across the Nordic countries. Finland has its own traditions, terminology and extraordinarily strong relationship with forests, lakes, cottages and outdoor life. We should not flatten those differences. But there is nevertheless a recognizable family resemblance.

The word friluftsliv is often translated into English as “outdoor recreation,” but the translation is inadequate. Recreation suggests a leisure activity separated from ordinary life. You go hiking, go camping, go skiing — and then return to normality. Friluftsliv can encompass all of those activities, but its cultural meaning is broader. It suggests that human beings should maintain an ordinary, habitual relationship with the outdoors. Indeed, the direct translation would be "free air life," indicating that living in and with nature is an integral part of life itself.

That assumption appears throughout Nordic life in forms that can seem so familiar that they become difficult to notice: children sleeping outside in prams; preschool groups spending much of the day outdoors; families disappearing to summer cottages; berry and mushroom picking; swimming from rocks and docks; skiing through forests; walking regardless of weather; sauna followed by a plunge into a lake; and traditions of public access that make forests and shorelines unusually open to ordinary people.

These practices did not all descend from children's summer colonies, nor should they be collapsed into a single historical tradition. But they share a family resemblance. Nature is not simply scenery. It is a place in which human life happens. And children are not merely visitors to it. They belong there too.

What the Photographs Preserve

This may be what makes photographs from the old summer colonies so compelling today. They preserve more than vanished buildings or forgotten organizations. They preserve a particular geography of childhood.

The children are outside almost constantly. They inhabit beaches and forests with an ease that can look startling from the perspective of a twenty-first-century childhood increasingly organized around indoor spaces, screens, schedules and adult supervision.

There is another striking quality to many of the photographs: the children often seem physically comfortable in their surroundings. They are barefoot. Wet. Muddy. Often naked while swimming and playing in the water. Lying on grass. Sitting on rocks. Crowded together on docks. Clothes and towels appear scattered around them. Their bodies seem less separated from the environment than ours often are today.

This does not mean that previous generations possessed some mystical harmony with nature. Nor does it mean that every child enjoyed being cold, wet, scratched by branches or bitten by mosquitoes. Children complained then too. But discomfort was not necessarily interpreted as evidence that something had gone wrong. Being wet because you had been swimming, muddy because you had been playing, or tired because you had walked a long way were ordinary consequences of having spent the day outdoors.

We should nevertheless be cautious when interpreting photographs. Historical photographs are selective. A smiling group on a beach cannot tell us whether somebody cried themselves to sleep from homesickness the night before. A photograph of barefoot children cannot tell us whether they had chosen to remove their shoes or simply lacked good ones. Nor should poverty, disease or the limited choices available to working-class families be transformed into picturesque evidence that everything was somehow better in the past. It wasn’t. But history allows us to notice what has changed without requiring us to wish ourselves back into it. And one of those changes concerns what adults believe children are capable of doing.

The Changing Boundaries of Childhood

The children in these photographs were not thought to require constant entertainment. Much of the time, the environment itself provided the entertainment. Nor were they necessarily expected to remain within immediate reach of a parent. They belonged to groups of other children, and those groups developed their own games, friendships, conflicts and adventures. A forest could occupy an afternoon. A shoreline could occupy a week. A summer could feel enormous.

Nor should we pretend that the greater physical freedom visible in these photographs came without risk. It did not. Historical accident statistics show that Nordic childhood was considerably more dangerous than it is today, and drowning in particular claimed far more children's lives. The children who swam from docks, wandered through forests and spent long stretches beyond immediate adult supervision inhabited a world in which serious accidents were more common. The difficult question is not whether modern safety measures have saved children’s lives—they clearly have—but whether every restriction on children’s independence that followed was necessary to achieve those gains.

The physical territory available to children has contracted dramatically in many affluent societies. Places once understood as ordinary environments for children — streets, woods, vacant lots, beaches and parks — increasingly become places children enter under adult supervision.

At the same time, children’s schedules have become more organized. Activities that once emerged informally are increasingly transformed into programs. Play becomes an extracurricular activity. Exercise becomes a sport. Exploration becomes an educational outing. Nature becomes a field trip. None of these things is inherently bad. But taken together they represent a subtle shift in authority over childhood. Adults increasingly determine not only where children will be, but what they will do when they get there. The old summer-colony photographs show another possibility.

Familiarity Rather Than Instruction

Perhaps this is the most useful way to understand friluftsliv today. It does not require rejecting modern life, abandoning cities or pretending that Nordic childhood in 1920 or 1950 represented some lost golden age. It asks something simpler. What happens when we stop treating nature as somewhere we occasionally take children and begin treating it as somewhere children belong?

The four brothers Broomé in the Stockholm archipelago in the early 1890s. The water may be chilly, hence their hesitation. Public Domain.

The distinction is subtle but profound. A scheduled hike can teach a child about nature. An afternoon spent wandering between water, trees and rocks teaches something slightly different: familiarity. And familiarity changes our relationship with the world around us.

A forest that has been visited on a school excursion is an interesting environment. A forest in which you have built shelters, become soaked in the rain, scratched your legs on branches, eaten sandwiches, argued with friends, discovered frogs and returned home muddy is something closer to a place. It becomes part of your own geography. The same is true of a shoreline.

Once you know which rocks are slippery, where the water becomes suddenly deep, where the tiny fish gather, which path leads back through the trees and which rock remains warm longest in the evening sun, you are no longer simply visiting nature. You know somewhere.

That knowledge is difficult to acquire through instruction because it is accumulated through repetition. Perhaps this is one reason friluftsliv can be difficult to export as a concept. It is tempting to turn it into another program: take children hiking, teach them outdoor skills, schedule more nature activities.

All of those things can be worthwhile. But they can also miss the underlying idea. The important thing may not be what children are instructed to do outdoors. It may simply be how much of their lives they are permitted to live there. The children's summer colony institutionalized that experience on an extraordinary scale. It took generations of urban children and, for several weeks each summer, relocated the center of their lives outdoors.

The World Beyond the Door

There is something worth recovering from that history. Not the poverty that made the first colonies necessary. Not the medical theories that sometimes accompanied them. Not the long separations from parents that some children undoubtedly found painful. And not every assumption about children or authority that belonged to another era. What is worth recovering is the confidence behind the experiment.

The adults who created the summer colonies believed that children could flourish with space. They believed that being outdoors mattered enough to organize institutions around it. They believed that children benefited from other children, from physical freedom, from temporary independence and from sustained contact with a world that had not been constructed entirely for them.

Perhaps most importantly, they did not imagine childhood as something that should occur exclusively under adult direction. That idea fits naturally within the larger philosophy behind the Community of the Cosmic Divine.

We spend a great deal of time examining the invisible assumptions that structure our lives: ideas about bodies, families, success, danger, respectability and what constitutes a “normal” life. Childhood is surrounded by such assumptions too. Many are so familiar that we no longer recognize them as assumptions. We assume children need to be watched. We assume their time needs to be filled. We assume useful experiences need to have identifiable educational outcomes. We assume that an adult should usually know where a child is and what the child is doing. Some of those assumptions exist for very good reasons. Others deserve examination.

The history of the children's summer colony offers a useful reminder that childhood has been organized differently before — and can therefore be organized differently again. Friluftsliv does not give us a formula for raising children. It offers something more modest and perhaps more valuable: another way of imagining where human beings belong.

The children staring back at us from those old photographs inhabited a world in which the boundary between ordinary life and the natural world was thinner than it often is today. They ate outside. Played outside. Worked outside. Quarreled outside. Got dirty outside. Learned what their bodies could do outside. And, over the course of long summer days, places that had initially been unfamiliar became their own. Perhaps that is the enduring lesson of the summer colony. Children do not necessarily need nature explained to them. Sometimes they simply need enough time in it for it to become home.
