Grundy Lake Provincial Park is a natural environment park near Britt, just off the Trans-Canada Highway, with lakes, beaches, mixed forest, camping, paddling, hiking, fishing, and education programs. Ontario Parks lists the park at 3,614 hectares, established in 1959.
The park sits in a transition landscape where Ontario Parks notes mixed forest marks the boundary between north and south. That gives Grundy Lake a classic road-trip feel: easy enough to reach, but still clearly part of the lake-and-forest country north of the busiest southern Ontario corridor.
Ontario Parks highlights camping choices for RV, car camping, and backcountry canoe-in sites; hiking trails; nearby canoe and kayak rentals; smooth rocky-shore beaches for swimming; many inland lakes for canoeing and kayaking; and Natural Heritage Education programming.
That range makes Grundy Lake a strong all-round camping park. Families can stay near beaches and services, paddlers can explore inland lakes, and campers looking for a quieter experience can consider canoe-in backcountry sites.
Plan around car camping, RV camping, roofed accommodation, backcountry canoe-in camping, canoeing, kayaking, swimming, beaches, hiking, fishing, biking, Natural Heritage Education programs, and road-trip stops along Highway 522 and the Trans-Canada route.
Visitors should check whether rentals, programs, beaches, and backcountry access are available for their exact dates.
Ontario Parks lists Grundy Lake day use, camping, and roofed accommodation from May 8 to October 13, 2026. Confirm reservations, backcountry availability, rental details, swimming conditions, trail access, alerts, facility hours, and park rules through the official Ontario Parks source before travelling.
