Georgian Bay Islands National Park (established 1929) consists of 63 small islands or parts of islands in Georgian Bay, near Port Severn, Ontario. The total park area is approximately 13.5 km2 (5.2 sq mi). Prior to the creation of Fathom Five National Marine Park, Flowerpot Island was also a part of the park.
The islands blend the exposed rocks and pines of the Canadian Shield with the hardwood forests found further south. The park can only be reached by boat; there are limited camping facilities on the largest island, Beausoleil Island.
It is part of the Georgian Bay Littoral Biosphere Reserve.
It is home to mammalian species such as woodland caribou, white-tailed deer, moose, black bear, coyote, timber wolf, lynx, bobcat, porcupine, raccoon, beaver, red and gray fox species, chipmunk, and red squirrel. This park also provides habitat for 33 species of reptiles and amphibians, including the hognose snake, the eastern fox snake, and the threatened eastern Massasauga rattlesnake. Some of the more isolated islands provide nesting areas for colonies of gulls and terns.
