Campgrounds and RV parks near Cardston County, AB

Cardston County sits in southern Alberta, with the town of Cardston about 32 kilometres north of the Montana border. The area works as a practical base for RV travellers heading to Waterton Lakes National Park, the St. Mary Reservoir, and the Chief Mountain border crossing into Glacier National Park. Camping options range from full-service private RV parks to rustic provincial sites. Covered Wagon RV Park offers a private option with full-service sites suited to larger rigs. Upper - St Mary Reservoir Provincial Recreational Area and Lower - St Mary Reservoir Provincial Recreational Area line the south shore of the reservoir, with sites suited to RVs and tents, some powered and shaded by trees, and some backing right onto the water. Police Outpost Provincial Park offers a no-service campground with 46 sites, pit toilets, and no running water at the sites. Chief Mountain Cabins & Campground rounds out the options closer to the Waterton corridor.

Provincial campgrounds in the area use the Alberta Parks reservation system at reserve.albertaparks.ca. Reservations at Police Outpost Provincial Park can be made 90 days in advance of arrival date, and the St. Mary Reservoir campgrounds also open 90 days ahead. Wally's campground at the St. Mary Reservoir provides a mix of both first-come, first-served and reservable campsites. For long weekends in July and August, book the moment the 90-day window opens. Cancellations are common, and tools that scan for openings can help fill gaps. Covered Wagon RV Park and Chief Mountain Cabins & Campground are private operators booked directly through their websites, which is the better path for guaranteed full hookups.
