Georgian Bay Islands National Park

Quick Navigation

Georgian Bay Islands National Park is part of the Georgia Bay which is a body of water located to the northeast of the main body of Lake Huron. The national park sits in the southeastern part of the bay.  The park covers an area of 5.2 square miles (13.5 sq km).

Whereas Lake Huron is a shared body of water between Michigan and Ontario, the Georgian Bay is entirely within the borders of Ontario. The bay extends 120 miles (190 km) long and reaches a width of 50 miles (80 km). The surface area covers 5,800 square miles (15,000 sq km) with an average depth of 150 feet (46 m).

The national park covers 63 islands that are scattered across the southeastern part of the bay along the shoreline of the bay. The largest of the islands is Beausoleil Island.

The 63 islands that comprise the national park area are part of a larger collection of about 30,000 islands scattered across the bay.  The national park and larger collection of islands are all part of the UNESCO biosphere reserved known as Georgian Bay Littoral.

The national park and surrounding ecosystem sustain a number of wildlife species where sightings add to any adventure.  Most people are interested in the mammal species and some of the more popular include beaver, black bear, bobcat, coyote, fox, lynx, moose, porcupine, raccoon, timber wolf, and white-tailed deer.

Rattlesnake is one of the surprising finds within the 33 different species of amphibians and reptiles. Although not renowned for birdwatching, the Georgian Bay Islands do have both nesting and migratory birds to observe while exploring the waterways.

The national park is only accessible by boat and the majority of activities are related to the water and navigating around and throughout the 63 islands of the national park.


The islands and unique landscapes that surround them are some of the highlights of the national park.  It is hard to imagine 63 islands in the national park, let alone 30,000 islands blanketing the area.
