Kalvebod Fælled (Vestamager)

A reclaimed seabed turned wild commons

Kalvebod Fælled, often called Vestamager, stretches across some 20 square kilometres of former seabed on the western side of Amager, directly facing Copenhagen’s skyline yet feeling a world away. The landscape exists thanks to an ambitious mid-20th-century land reclamation project: a long dyke, canals and pumps transformed shallow coastal waters into dry land. Initially used as a military training ground, the area was gradually handed over to the environmental authorities and fully opened to the public after clearance of unexploded ordnance. Today this once utilitarian project has softened into an expansive, low-lying plain where big skies dominate. The ground underfoot hints at its maritime past: damp, salty soil, shallow ponds and reed-fringed channels that shimmer in the wind. The openness is striking, especially so close to a capital city, and it is this sense of space that gives Kalvebod Fælled its distinctive character.

Wetlands, birch woods and grazing herds

The great appeal of Kalvebod Fælled lies in its variety of habitats. Wide meadows blend into brackish marshes, while small lakes and boggy hollows punctuate the plain. To the south and east, raised dykes carry paths with long views over the wetlands and out towards Køge Bay. In contrast, areas like Pinseskoven surprise visitors with light, airy birch forest that seeded itself naturally once the seabed had dried. Livestock is a constant presence. In summer, hundreds of cattle and horses graze freely, joined year-round by hardy sheep that keep scrub in check and maintain the open grassland. A sizable population of fallow deer moves quietly between thickets and open fields, often visible at dawn or dusk. Their presence, together with the livestock, lends the reserve a pastoral feel more reminiscent of old commons than a carefully designed city park.

A bird sanctuary on a migration highway

Kalvebod Fælled is one of Denmark’s notable bird areas and forms part of the EU’s Natura 2000 network. Its location on a key north–south migratory route means that, depending on season, the wetlands can be busy with waders, ducks and geese. Species such as marsh harrier, dunlin, pintail and Arctic tern regularly pass through or breed here, while winter brings concentrations of mute swans and diving ducks to the lakes and coastal shallows. Part of the southwestern corner is a closed bird sanctuary, off-limits to visitors to protect sensitive wildlife. Instead, birdwatchers are guided to bird towers and hides positioned around key lakes like Klydesø and Store Høj Sø, as well as along the coastal dyke. From these vantage points, you look across reeds and shallow water where herons, bitterns and, with some luck, white-tailed eagles may be seen hunting.

Nature Centre Amager and active exploration

Near the main entrance by Vestamager metro station, Nature Centre Amager serves as the gateway to the reserve. Here you find exhibitions about the area’s history and wildlife, practical information, and an equipment-rental hub offering bicycles, roller skates and nature-exploration gear. A cosy café next door serves organic meals, coffee and cakes, with outdoor seating that overlooks the meadows. From this hub, waymarked trails radiate into the landscape. Three main hiking routes of roughly 3.5 km, 6 km and 8.8 km provide accessible circuits across meadows, canals and birch stands. Cyclists enjoy a web of gravel and asphalt paths ideal for longer loops, while runners use the traffic-free, flat terrain for extended training. For families, the Himmelhøj nature playground, inspired by the four elements, offers climbing structures, sculptural logs and campfire sites that encourage imaginative outdoor play.

Space for overnight stays and quiet contemplation

Despite its proximity to urban Copenhagen and the futuristic blocks of Ørestad, Kalvebod Fælled retains pockets of deep quiet. On still evenings the only sounds might be distant cows, wind in the grasses and the calls of wading birds. Clear nights reveal an impressively starry sky by city standards, helped by the lack of tall buildings and streetlights across much of the reserve. For those who want to linger, simple shelters and basic campsites are dotted around selected forested edges and lakesides, allowing overnight stays under canvas or wooden roofs. Campfire sites near the playground and in small clearings create natural gathering points, while long, straight paths are perfect for unhurried reflection. Whether you come for birdwatching, a full-day bike ride, a family outing or simply to walk in open air until the city feels distant, Kalvebod Fælled offers an unusually wild experience on Copenhagen’s doorstep.
