Mjölhatteträsk and Valar

Two kilometers west-southwest of Burgsvik lies a broad area consisting of marshes and Gotlandic alvar. In this area is Mjölhatteträsk, a 90-hectare large, shallow marsh that, together with Inre Stockviken, is Gotland's southernmost lake. It is situated only 1.7 meters above sea level on layers of marly limestone.

Because Mjölhatteträsk is located so far south, it is often the first place migratory birds arrive at during their migration. Ducks, geese, terns, waders, and swans nest here.

Due to the fertile land on the western side of the marsh, a large and magnificent birch forest has been able to grow. On the southern shore, a dense deciduous forest teeming with life takes over. Various deciduous forest birds are gathered here, such as the rosefinch and the marsh warbler.

A bit west of Mjölhatteträsk, between Killingholm and Valar, lies an interesting and beautiful stretch of coastline. The beach is largely made up of sandstone and occasional pieces of "oolitic limestone." The sea has given the sandstone a unique appearance with beautiful patterns and strange formations.
