Stroll along one of the Forest’s four interpretive nature trails ranging in length from 0.5 (0.8 km) to 2.5 miles (4 km) and learn more about the area's history, wildlife and plants. Take a guided hike led by a naturalist or participate in one of the many programs offered at the Lake Nature Center and Clear Lake Campground from June through August.

Looking for something more adventurous? Hike one of the seven designated hiking trails, old logging roads, forest access roads or snowmobile trails or bike nearly 40 miles (64 km) on marked trails. For a serious dose of adventure test your family's skills on remote and challenging mountain bike trails.

An official site on the Great Wisconsin Birding and Nature trail, the Northern Highland - American Legion State Forest is also a birdwatcher's paradise. Spot a blue jay, loon, bald eagle or one of the other 241 species that inhabit the forest. Wildlife viewing extends beyond bird watching. Catch sight of a deer, beaver, otter, fox, coyote or perhaps even a black bear.

The forest is not just a summer destination. From December through March, outdoor enthusiasts will enjoy over 40 miles (64 km) of groomed and marked cross country ski trails, 30 miles (48 km) of winter use trails and over 400 miles (643 km) of snowmobile trails.

Facilities at the Crystal Lake, Clear Lake, Indian Mound and Little Star Picnic Areas include drinking water and vault toilets. All four picnic areas have swimming beaches. There are eighteen family, five wilderness and over one hundred canoe campsites within the forest.
