Lake St. Peter Provincial Park campground sits on a 478-hectare park near the village of Lake St. Peter, roughly 25 minutes south of Algonquin Provincial Park's East Gate in Ontario.

The campground offers 65 car-camping sites set within mixed forest, including waterfront, electrical, and non-electrical options, with many sites large enough to accommodate trailers.

Shared facilities include vault toilets, drinking water taps throughout the campground, and a centrally located comfort station with flush toilets, showers, and coin-operated laundry. A boat launch, sandy beach, and picnic area round out the on-site amenities.

Two hiking trails and a large lake suitable for canoeing, kayaking, and fishing make it a well-rounded destination for paddlers and outdoor enthusiasts seeking a quieter alternative to nearby Algonquin.
