Grundy Lake Provincial Park

Grundy Lake Provincial Park is located between Georgian Bay and Lake Nipissing. It is situated on the Canadian Shield and contains rocky outcrops, wetlands, and a few inland lakes. Grundy Lake offers a variety of activities on and near the water, including swimming, fishing, boating, paddling, camping and hiking.

We’ve visited Grundy Lake twice:

Hiking Trails

There are three hiking trails in Grundy Lake, all of which are signed with yellow markers on trees or yellow circles on the rocks:

(1) Beaver Dams Trail (3.6km round trip, rated moderate to difficult). The trail consists of two interconnecting loops and passes through a dense forest and wetlands.

(2) Gut Lake Trail (2.5km loop, rated moderate to difficult). The trail cross rocky outcrops along the shoreline of Gut Lake, weaves through the forest, and passes by a marsh.

(3) Swan Lake Trail (1.5km loop, rated moderate to difficult). The trail crosses a floating boardwalk over Swan Lake before weaving over, up, down and around large exposed rocks. Along the way there are nice views and lookouts of the wetlands.

Activities and Attractions

Grundy Lake also features:

  • Six sandy beaches for swimming
  • Cliff jumping at Gut Lake (we have yet to try this, but we’ve see other people do it)
  • A picnic area with a sheltered section near the beach
  • Canoeing

Camping

Grundy Lake offers car camping in nine campgrounds, two of which are in a radio-free zone, and backcountry camping at ten campsites that are accessible by canoe. We’ve camped here before in June 2020 and had a wonderful time.
