Natural Features
Four islands in Lake Nipissing, 10 kilometres southwest of North Bay, make up the park. The islands represent the island ecology in Lake Nipissing with warmer than normal regional temperatures. The islands support basswood, three species of ash, silver maple, birch, cedar, burr oak and sugar maple. Thickets of poison ivy, striped maple, chokecherry, and ground hemlock are common. The islands are import to over 50 species of breeding birds and include Great Blue Heron colonies, and osprey nesting sites. Great Manitou Island has a sand beach.
Mineral exploration activities resulted in subsurface and surface disturbance on two islands. Little Manitou Island has a small limestone kiln used during the construction of the North Bay portion of the Canadian Pacific Railway.  Uranium deposits were explored with a mine headframe and 135 m of vertical shaft on Newman Island between 1953 and 1960 but the deposits were never brought into production.

Park Facilities and Activities
The park has no facilities but the park’s sand beach is available for day use only.  Visitors can enjoy swimming, boating and nature viewing.
If visiting the islands please do not disturb nesting birds. Poison ivy is common in most vegetated areas.
