Founded in 1937, The Ridges Sanctuary is recognized as one of the most diverse natural areas in Wisconsin. Five miles of hiking trails wind through over 1400 acres of boreal forest and provide access to the unique ridge and swale complex formed by the steady rise and fall of the waters of Lake Michigan.

Home to 500 species of plants, 60 species of birds and 12 threatened or endangered species like the Hine's Emerald dragonfly. The Sanctuary is also the location of two iconic Baileys Harbor Range Lights, which were built to keep ships off the treacherous reefs and shallows at the entrance to Baileys Harbor.

Trails are open year around for hiking, including a fully accessible boardwalk that spans a third of a mile, snowshoeing and cross-country skiing. Check their website for educational programs and upcoming events.
