Bolund by Roskilde Fjord – Ice Age landscape, hiking and birdlife
Bolund is a protected peninsula north of Risø on Roskilde Fjord in eastern Denmark. The landscape was shaped during the last Ice Age and consists of a flat top, steep slopes, and a narrow land strip connecting the peninsula to the mainland. The area combines geology, nature, and cultural history and is now part of the Skjoldungernes Land National Park.
A remnant of the Ice Age – the landscape of Bolund
Bolund is a moraine hill formed by glacial movements more than 10,000 years ago. It rises about 12 metres above the fjord and stands out due to its steep slopes and narrow land connection. The area has been protected since 1941 because of its unique geological and scenic value.
Nature and flora by Roskilde Fjord
Access to Bolund goes through Lille Valby Enge, a protected salt meadow where grazing cattle help maintain the open landscape. Here, you’ll find plants such as thrift, early marsh orchid, kidney saxifrage, and the rare interrupted fern. The area is also known for a rich variety of fungi, including waxcaps, parasol mushrooms, and wild field mushrooms.
Birdwatching at Bolund – white-tailed eagles, swallows and terns
Bolund is an important habitat for birds. Sand martins nest in the cliffs, and the fjord attracts a wide range of species throughout the year. In summer, you may see common terns, black-headed gulls, and swans. In winter, geese, coots and diving ducks gather. White-tailed eagles and peregrine falcons are also regularly spotted above the area.
