This hilly, protected environment lies off the beaten track. Geological features found here include a ground moraine deposited by the last glaciation, and middle to late Precambrian rocks, part of the central gneiss belt. The park's ecological diversity features extensive upland forests of Sugar Maple, Hemlock and Yellow Birch, and low-lying swamps, marshes and meadows. Protected places such as Bigwind Lake are sensitive to damage and overuse. Visitors are welcome but are asked to respect the ecosystem. The park, open for day-use only, has no facilities for visitors.
