Upper St. Mary Campground sits along the shores of St. Mary Reservoir in southern Alberta, offering scenic views of the reservoir and the mountains to the south, along with notably dark nighttime skies.

The campground accommodates both tents and RVs, with a mix of first-come, first-served and reservable sites. A few sites benefit from shade trees, and a boat launch provides direct access to the reservoir.

Water recreation is a draw here, with opportunities for boating, sailing, windsurfing, water-skiing, and canoeing on the reservoir.

The campground remains open into the off-season, though services are not available during that period and campers should arrive fully self-sufficient.
