Bagsværd Lake

Surrounded by forests, hills, parks, meadows, alder swamp and cultural gems, Bagsværd Lake has something for just about everyone. It has designated running routes, plenty of space for long walks and cycling, as well as boating on the lake, which is also home to the national rowing stadium.  On one side is the prime minister’s official residence, Marienborg, on the other, Denmark’s first radio transmitter, which is still in use today.

Human activity in this area has been recorded stretching back about 2,000 years. A thousand years ago, the lake was used as a millpond and powered some of the very first water mills.

Today, it is a great place for long walks, or there is always the monthly fun run organised by the local athletics club. Relax and enjoy the sunshine, a picnic and nature at the ruined castle in Aldershvile Castle Park.

Explore the unique Ellesump swamp at Radiomarken field. Or step inside the former country seat, Sophienholm, which offers a varied calendar of art exhibitions. Canoes and rowing boats are available for hire, and there is a boat service that runs throughout the summer season.

On summer nights, bats swarm around the lake, where metre-tall flowering aquatic plants spread over the surface and goldeneye ducks nest along the banks.

If you’re lucky, you might see ospreys, kingfishers and goshawks. With a few restrictions, permits are available to fish for zander, roach, perch, pike, carp and bream. Or you could just watch the national rowing team, one of the best in the world, train out on the lake.
