This semi-wilderness park features Canadian Shield granite outcrops, vast wetlands, 28 lakes, mixed forests, plants and wildlife. Trails wind through rugged terrain to areas such as: Moulton Gorge, Arkon Lake Bog, the Black Lake homestead and the Crab Lake mines.
From Otter Lake, hikers and canoeists head into the interior for glimpses of osprey and kingfisher, deer and black bear, coyote, fox, and abundant beaver. Some of the many unique features along the trails include lookouts, beaver ponds, abandoned mica mines, the remains of a homestead, extensive boardwalk and rock ridges. Wilderness skills courses are offered throughout the year; some by the Friends of Frontenac Park
