Welcome to Stendörren

Stendörren is a popular, well-known nature reserve that attracts visitors from near and far. There is a range of environments – from nutrient-rich shore meadows to rocks with windswept pine trees. Stendörren is on Sweden’s east coast between Nyköping and Trosa.

Several suspension bridges take you far out into the natural environment of the archipelago. You can rest on the rocks and enjoy the sea view, or swim in the sea. You can only reach the outer skerries in the reserve by boat or kayak.

Explore the nature reserve on foot along one of several marked trails. Some of the trails have interesting information boards on nature and culture.

The aim of the reserve is to secure access to the coast and archipelago for outdoor pursuits, to preserve the character of the area as an old farming and archipelago landscape, and to protect the wildlife.

The Stendörren nature reserve was formed in 1972 and covers 923 ­hect­ares, of which 738 hectares is open ­water. The land is owned by the Environmental ­Protection ­Agency and managed by the County ­­Administra­tive Board in ­Söder­manland County. The area is a part of the European Natura 2000 protected areas network.

Nature

On the shore meadows you will find seaside centaury, strawberry clover and silverweed, and in the stonier parts sea milkwort and valerian. The bare rocks are the ideal home for chives, yellow stonecrop and wild pansy.

The water in the Baltic Sea is brackish, so neither fully salty or fresh. If you look below the sparkling surface you can discover jellyfish, large shoals of bleak and perhaps even the seahorse-like pipefish.

There are also many sea birds in the reserve. Common tern, eider, herring gull, goosander and oystercatcher are some of the ones you may encounter. If you’re in luck you may see a white-tailed eagle as it soars in the sky, or a grey seal sunbathing on a rock.
