The Big Whiteshell Lake boat ramp sits within Whiteshell Provincial Park in southeastern Manitoba, roughly 66 km from Seven Sisters via Highway 309.

There are two launch points serving the lake: one at the South Shore Campground and one at the end of Highway 309. The South Shore location is the primary hub, with parking available in an overflow lot across the highway.

The South Shore launch offers straightforward access to Big Whiteshell Lake, which stretches approximately 7 km long and 3. 5 km wide, with central depths averaging 7 m and some areas exceeding 12 m.

A beach and playground are located beside the launch, making it a popular spot for families. A public boat launch also sits adjacent to a nearby resort on the lake.

The ramp serves as the put-in for the White Shell Lakes canoe loop route and is a common departure point for anglers targeting Northern Pike, Walleye, and Perch.

Note that the North Shore launch has been subject to temporary closure due to ice damage, with boaters directed to the South Shore Campground launch during repairs.
