Ridges Sanctuary Natural Features

The Ridges Sanctuary, a National Natural Landmark, named for its distinctive topography, is a series of 30 narrow, crescent-shaped sandy ridges and swales where 500 different types of plants, 60 types of birds and 12 endangered species flourish. Explore this natural treasure by hiking on its trail system. One trail goes by the historic Baileys Harbor Range Lights built in 1869. They are the only lighthouses of this design still functioning as navigational aids.
