Rock Lake is located north of Cartwright in southern Manitoba, situated approximately 4 miles east off Highway 5 on Mile 14N. The lake supports boating, fishing, and swimming during the summer months, making it a multi-use water body where paddlers will share the water with other recreational boaters and anglers.

Access to the lake is available via the Rock Lake Beach area, which includes a boat launch. The Rock Lake Beach Store and coffee shop operates year-round and offers fishing licenses, seasonal lot rentals, and full-service camping, making it a practical resource for paddlers needing supplies or information before heading out. Camping is available on site, which supports multi-day visits. For camping and facility inquiries, the Rock Lake Beach Store can be reached at 204-529-2365.

Summer is the primary paddling season, when swimming, boating, and fishing activity is at its peak. Winter use of the lake shifts to ice fishing, indicating the lake freezes reliably in colder months. The Rock Lake Nature Trail, located near the beach area, is open year-round and offers an opportunity to explore the surrounding landscape on foot in conjunction with time on the water.

Paddlers planning a trip to Rock Lake are encouraged to contact the Rock Lake Beach Store directly for current details on water conditions, access, and any local regulations before visiting.
