The Loon and Grass Lake Boat Ramp provides water access to Loon Lake in the Almaguin Highlands, near the Town of Kearney, Ontario, approximately three hours north of Toronto.

An informal public boat launch is located near the dam that connects Loon Lake and Grass Lake, with water levels controlled by a Ministry of Natural Resources-owned and operated dam.

The lake offers excellent conditions for boating, canoeing, and kayaking across roughly 8 km of shoreline, with crystal clear waters reaching a maximum depth of 29 metres.

Anglers will find a variety of fish species including Lake Trout, Brook Trout, Smallmouth Bass, Round Whitefish, Burbot, and White Sucker. The surrounding landscape features scenic rock outcroppings, pines, and towering trees.
