Your Membership Matters

Grindstone Park is a serene cottage community nestled within the wilderness on the mainland peninsula along the west shore of Lake Winnipeg. The community comprises over 400 cottages, just a 45-minute drive north of Riverton on Provincial Highway 8. Taking a quick turn onto Grindstone Road leads you through five subdivisions, all interconnected by scenic walking trails that promise exhilarating wildlife encounters for all ages. Numerous islands surround Grindstone Park, including Black Island, Goose Island, Deer Island, Punk Island, and Little Punk Island. It’s also a mere 20-minute boat ride from Hecla Provincial Park, which boasts a beautiful 18-hole golf course.
