The Beaver Basin Wilderness includes 13 miles of stunning Lake Superior shoreline from Spray Falls on the west to Sevenmile Creek on the east. The wilderness is some 3.5 miles deep and contains three beautifully clear lakes -- Beaver Lake - 762 acres, Trappers Lake - 45 acres, Legion Lake - 35 acres -- and five cold water streams -- Lowney Creek, Arsenault Creek, Sevenmile Creek, Little Beaver Creek, and Beaver Creek. These clear streams and extensive wetlands provide habitat for native coaster brook trout and other fish. Popular fish species include brook trout, largemouth, smallmouth and rock bass, northern pike and white sucker. An old growth cedar swamp exhibits healthy regeneration, an important browse species for white-tailed deer. Extensive beech-maple upland hardwood forest provides habitat for numerous mammals, birds, and flowering plants including black bear, timber wolf, American marten and fisher, migrating songbirds, raptors (such as bald eagle, barred owl, peregrine falcon, waterfowl and upland game birds), and spring wildflowers. An interesting pattern of glacial geology includes post-glacial meltwater channels, escarpments, and Lake Nipissing beach ridges.
The Beaver Basin Wilderness offers opportunities for quiet, solitude, wilderness recreation, and spiritual renewal. Individual and small group recreation is available along 8.4 miles of the North Country National Scenic Trail and 8.5 miles of connector trails as well as 6 backcountry campsites.
