Lake Fillingsjön offers a multitude of sports fishing settings and is also the perfect size for a week of fishing. Pike, perch and whitefish join to make the lake interesting.
Lake Fillingsjön has lightly brownish water that is relatively clear for much of the year. There is a wide range of species and the surrounding offer a mix of forest and agricultural areas. There are a few smaller islets and skerries, as well as a number of shallow coves. A plus is that the lake has a number of larger to and from flows from larger and smaller streams. Some housing can be seen from the lake at Strand, Fillingen and Gottarsbyn villages, but by en large the handsome, smaller farms blend well in the landscape around the lake. Beyond that the area is dominated by woods.
