The Narcisse Snake Dens is a provincial wildlife management area located in the Rural Municipality of Armstrong about 6 km (3.7 mi) north of Narcisse, Manitoba. The dens are the winter home of tens of thousands of red-sided garter snakes (Thamnophis sirtalis parietalis). These pits are the largest known concentration in the world of this particular type of snake. Their winter dens are caverns formed by the area's water-worn limestone bedrock. In the spring, they come up from their dens to the snake pits, where they mate, then they disperse into the nearby marshes for the summer.
