The Brereton Lake Boat Ramp is a public launch facility situated near South Beach at the south end of Brereton Lake, within Whiteshell Provincial Park, Manitoba, off Highway 307 approximately 6 km north of Rennie.

The ramp includes a dock for easier water access and is conveniently positioned close to the beach and a playground, making it a practical choice for families.

Anglers launching here have access to a productive fishery stocked regularly with walleye, alongside naturally occurring northern pike, smallmouth bass, yellow perch, and black crappie.

First-time boaters should note that the lake has numerous submerged rocks in shallow areas that are not marked with buoys.
