The largest island included in the national lakeshore, it is host to numerous trails and campsites. The island is known for its unique lagoon ecosystem with multiple carnivorous plants and low bush blueberries, as well as the singing sand found in Julian Bay.[2] Stockton Island also has one of the highest concentration of black bears in North America,[3] with a 2002 study finding 26 bears on the island (0.64 bears/km2).[4] The Trout Point Logging Camp is located on the island.
