Slave Lake shoreline

Due to its location on a major fly-way for migrating birds, Lesser Slave Lake is popular with birders.[4] The nearby Lesser Slave Lake Provincial Park has lakeside camping facilities located along sand beaches, with some rocky beaches as well. Fishing is popular and legal. The entire north shore of the lake is protected, other reserves being Hilliard's Bay Provincial Park, Lesser Slave Lake Wildland and Grouard Trail Park Reserve.

Highway 2 and the Canadian National Railway follow the southern shore of the lake, and the Bicentennial Highway has its southernmost point at eastern end of the lake.

A number of Indian reserves are established at the shores of the lake:
