Wally's Campground sits along the eastern shore of St. Mary Reservoir in southwestern Alberta, part of St. Mary Reservoir Provincial Recreation Area.

The 52 unserviced sites offer open water views, strong stargazing conditions, and direct access to the adjacent Wally's Day Use Area and its sandy beach.

Most trees on the grounds are newly planted, though a handful of mature trees provide shade at select sites. Firepits and pit/vault toilets are available; campers must bring their own water.

Swimming and beach access are best from May through mid-July when reservoir levels are high. By August, the waterline can recede significantly, leaving the shoreline muddy.

An interpretive loop trail near the site offers a short walk with paleontological significance — the Wally's Beach area is known for late Pleistocene fossil trackways and Paleoindian archaeology exposed when the reservoir was partially drained in 1998.

The campground season typically runs mid-May through early September.
