Situated in the Big Muddy Badlands, Castle Butte is a free-standing structure with a circumference of 0.5 km and an elevation of 60 m. A relic from the Ice Age, it is a striking formation that served as a landmark for Indigenous people, the North West Mounted Police (NWMP) and early Canadian settlers. Composition is sandstone and clay-based with alkali and coal deposits.
Castle Butte is located on private land and only open to the public from June 1 to November 1. Access outside of these times is prohibited, as it can negatively affect calving season. If visiting during the open season, please remember to respect the environment; take only pictures, leave only footprints. Protecting and respecting this natural attraction is the only way to ensure it will continue to be made available for visitation.
