Cadomin Cave

Cadomin Cave is a natural limestone cave in Leyland Mountain near Cadomin, Alberta, in the Canadian Rockies. Known since the early 1900s and likely earlier to Indigenous peoples, it was mapped in stages from 1959 onward, with later discoveries greatly extending its known passages, depth, and decorated sections such as the Crystal Crawls. Easy upper access made it popular for generations, but heavy visitation also left it among the region’s most vandalized caves. Its modern importance centers on protection and stewardship: it was placed under Alberta Speleological Society care, included in Whitehorse Wildland Provincial Park, and closed to people in 2010 to protect overwintering bats from white-nose syndrome.
