Lake Rosjön is a narrow lake in north-south direction and is rich in islands, islets, capes and bays, which means a lot to explore for the fishing enthusiast and many picnic places for those who are more interested in a cup of coffee. Road 32 between Eksjö and Aneby passes relatively close by the east side of the lake and there are also more houses on that side than on the west side.
Lake Rosjön is located around 6 kilometres north from Eksjö and the southern parts of the lake is in the municipality of Eksjö. Rosjön Fishing Area also offers fishing in the small Lake Rogölen, just north from Lake Rosjön.
