Peterson's Beach Recreation Site sits on the north shore of Fraser Lake in British Columbia, roughly 22 km around the west side or 30 km around the east side of the lake.

It serves as one of three public boat launches on Fraser Lake, which covers 22 square miles of surface area and reaches a maximum depth of 100 feet.

The site is a gated, 40-unit recreation area set in a sheltered bay with a sand beach stretching over 800 metres. Amenities include a cement boat launch, an accessible outhouse, and a hiking trail.

A trailhead for additional hiking is located across the road to the right of the parking lot. The site is listed under BC's Recreation Sites and Trails program and is a popular base for fishing Fraser Lake's Rainbow Trout, Lake Trout, and Burbot.
