About Ossa Mountain National Park

Ossa Mountain National Park in Maine offers rugged mountain terrain, dense forests, and scenic vistas, making it a favorite destination for hiking, climbing, and wildlife viewing enthusiasts.

Wilderness Landscape & Natural Heritage

Ossa Mountain National Park, located in mid-coast Maine, covers an extensive area of forested mountains, ledges, and freshwater lakes. The park centers around Mount Ossa, the highest peak in Maine at 5,270 feet, offering panoramic views of the surrounding wilderness and distant Atlantic coast. The park's landscape is characterized by mixed hardwood and conifer forests, alpine zones near the summit, and rocky outcrops. Diverse ecosystems support species such as moose, black bear, peregrine falcons, and rare alpine plants. Historically, the area was inhabited by the Wabanaki peoples and later became a logging region before conservation efforts led to its designation as a national park in 1995. Outdoor recreation is the park's highlight, featuring extensive hiking and backpacking trails, mountaineering routes to the summit, and freshwater fishing in remote ponds. Notable features include the challenging Ossa Mountain Trail, serene Tumbledown Pond, and the scenic Wild Stream Gorge. The park attracts visitors seeking wilderness solitude, rugged terrain, and scenic beauty. Its remote location and elevation changes offer excellent opportunities for seasonal activities like fall foliage viewing and snowshoeing in winter. Visitor facilities include trailheads, backcountry campsites, and basic information kiosks.
