Red Rock Coulee

Red Rock Coulee Natural Area is 324 hectares (800 acres) of badlands, hard sandstone capped hoodoos and large, round, red boulders. Formed in prehistoric seas as layers of sand calcite and iron oxide collected around a nucleus formed by shells, leaves, or bones. These concretions grew larger as the circulating waters deposited more layers. The reddish colour comes from iron oxide. At up to 2.5 metres (8 feet) in diameter, they are among the largest in the world. Along with the exposed rocks, you will also find prairie inhabitants such as deer, coyotes, rabbits, rattlesnakes, and nighthawks.

To reach Red Rock Coulee, drive southwest from Medicine Hat on Highway 3. Just before the village of Seven Persons you will turn south on Highway 887 secondary highway towards Manyberries. Continue south on Highway 887 until you reach Red Rock Coulee, which is open year-round.
