Ridges Sanctuary is Wisconsin's oldest private nature preserve, offering diverse ecological communities and scenic boardwalk trails along the shores of Lake Michigan.
Located on the northern tip of the Door Peninsula in Wisconsin, Ridges Sanctuary protects over 1,600 acres of unique natural habitats including boreal forests, sphagnum bogs, fens, and dunes. The Sanctuary is recognized for its geological ridges formed during glacial retreat, which create varied microhabitats. Originally founded in 1937, it was established to preserve rare plant species and delicate ecosystems that are uncommon in the region. Visitors can explore an extensive network of boardwalk and hiking trails that traverse a range of habitats, including old-growth white cedar and balsam fir. The Sanctuary is a hotspot for botany enthusiasts, as it is home to over 850 native plant species, including several orchids and carnivorous plants. Bird watchers frequent the area to observe migratory songbirds and other wildlife such as foxes and white-tailed deer. Notable landmarks include the Ridges Ancient Cedar Forest and the sphagnum bogs which are crucial for rare orchids. Seasonal wildflower blooms, especially in spring and early summer, offer spectacular photographic opportunities. The Sanctuary also provides educational programs and guided tours that align with conservation efforts. Its lakeshore location offers scenic views of Lake Michigan’s waters, and the combination of ecological richness and accessible trails make it an appealing destination for hiking, nature study, and peaceful outdoor recreation.
