The Lakes, Køge Travel Guide

The Copenhagen Lakes were not always the peaceful recreational spaces they are today. Their creation was rooted in military strategy and urban defense. After the city was besieged in 1523, Copenhagen's fortifications were strengthened through an ingenious system of dams and water barriers. The first dam raised the water level to create additional defensive perimeters, and by the early 1600s, Saint Jørgen's Lake was constructed through further damming of small streams. This allowed the city to flood the surrounding area when necessary to protect against invasion from the west. What began as a strategic necessity evolved over centuries into one of Copenhagen's most cherished public spaces, where the original purpose of defense has given way to a different kind of protection—a sanctuary from urban life.

The lakes consist of three interconnected bodies of water, each with its own personality. Sankt Jørgens Sø, the deepest of the three, features gently sloping sides that create a more gradual transition to the water. Peblinge Sø and Sortedams Sø, by contrast, are bordered by vertical granite edges and reach depths of approximately 2.5 metres. Two small islands—Fiskeøen and Fugleøen—have been constructed within Sortedams Sø and serve as vital breeding grounds for the diverse bird species that inhabit the area. The complete circuit around all three lakes stretches 6.35 kilometres, a distance that can be covered on foot, by bicycle, or at a leisurely jog, depending on your pace and inclination.

The lakes reveal different faces throughout the year, each season offering distinct experiences. In winter, when conditions permit, the frozen surfaces occasionally become thick enough for skating and walking—a rare and magical occurrence that transforms the lakes into a winter wonderland. Residents emerge to build imaginative ice sculptures, and the city occasionally permits supervised skating when ice conditions are safe. As temperatures rise and spring approaches, the sunny side of Queen Louise's Bridge becomes crowded with locals practicing "bridging"—a beloved Scandinavian pastime of sitting on the pavement with takeaway coffee and food, soaking in the warmth. Summer brings the most vibrant activity: joggers, walkers, couples, families feeding ducks, and friends gathering on the grassy banks for impromptu picnics. Even on the coldest winter days, when the sun shines, Copenhageners bundle up in winter coats and wool blankets provided by the outdoor cafés that line the lakes' edges, demonstrating the locals' unwavering commitment to outdoor socialising regardless of season.

The lakes function as a sanctuary for diverse bird species, making them a paradise for birdwatchers and nature lovers. Ducks, seagulls, swans, and numerous other waterfowl make their homes here, particularly around the breeding islands. The abundance of birdlife is one of the lakes' defining characteristics, and visitors are encouraged to bring binoculars for closer observation. The peaceful water environment and protected breeding grounds ensure that the lakes remain a vital habitat for Copenhagen's avian population, adding layers of natural richness to what might otherwise be simply an urban recreational area.

While the lakes offer tranquility, they are far from isolated or empty. They represent the social heartbeat of Copenhagen's inner neighbourhoods, particularly Nørrebro and Østerbro. Locals run, walk dogs, cycle, and simply watch life unfold along the paths. The area is dotted with cafés and restaurants where visitors can quench their thirst and hunger without leaving the lakeside experience. Whether grabbing a to-go coffee, enjoying brunch with a view, or dining at sunset, the culinary offerings enhance the recreational experience. The Lake Pavilion, an ornate building constructed in the 1890s for the Ice Skating Club, now houses a nightclub and restaurant, bridging the lakes' historical past with contemporary leisure culture.

What makes the lakes truly special is their seamless integration into Copenhagen's urban fabric. They are not remote or difficult to reach; rather, they form a gently curving arch through the inner city, making them accessible to residents and visitors alike. The well-maintained path system accommodates pedestrians, cyclists, and runners equally, and the infrastructure supports year-round use. From above, the lakes appear as five distinct bodies of water, though they are connected beneath dams and bridges, creating a unified recreational corridor. This accessibility ensures that the lakes serve not as a tourist attraction requiring special effort to visit, but as an everyday refuge that Copenhageners integrate into their daily routines.
