Main image

Lake Bästeträsk is a freshwater lake on the Swedish island of Gotland in Gotland County. It is the island’s largest inland lake and an important local freshwater habitat.

The shoreline and shallow waters attract birdwatchers and anglers; the lake’s open areas and reed margins support waterfowl and other wetland species. There are informal access points for walking along sections of the shore.

The lake is a natural coastal plain lake formed in the post-glacial landscape of Gotland and has been used locally for fishing and as a freshwater resource for nearby farms and settlements.

Geographically it lies in the northern part of Gotland, within Gotland County, surrounded by low limestone fields and farmland rather than mountainous terrain.
