Castle Mountain's summit reaches 2,273 metres, dropping 863 vertical metres to a base at 1,410 metres across 94 runs spread over roughly 1,453 hectares near Pincher Creek, Alberta. Terrain splits 55 per cent advanced, 21 per cent intermediate, 14 per cent expert and 10 per cent beginner, with average annual snowfall of roughly 8.1 metres. The resort carries Indy Pass affiliation. Seven lifts, including two double chairs and two triple chairs, serve the mountain alongside two t-bars and one surface lift.

Castle Mountain holds a genuinely distinctive place among Canadian resorts as one of the few remaining community and shareholder-owned ski areas in the country, a structure born from local skiers rescuing the resort from municipal ownership in the 1990s. Its heavily advanced-weighted terrain and comparatively light crowds have built a loyal following among skiers seeking an authentic, uncommercialised mountain experience.

Swiss immigrant Paul Klaas first discovered the area on horseback before developing the resort, which opened to the public in December 1965 with T-bar lifts installed that summer and a Swiss-style base lodge. Mount Baldy Ski Resort took ownership in 1972, and the area, then known as West Castle, hosted alpine events at the 1975 Canada Winter Games before the original day lodge burned down in January 1977.

The Municipal District of Pincher Creek subsequently owned and operated the resort until 1996, when the Westcastle Supporters Association, a trust of local skiers, took over and incorporated Castle Mountain Resort Inc. The resort remains a privately controlled corporation with roughly 150 shareholders, around 80 per cent of whom are local residents. Adult daily tickets run from 95 to 120 Canadian dollars.
