Turtle Mountain Provincial Park grooms 34 kilometres of trails for winter use. For 2019-2020, the park has new grooming equipment and is now grooming 28K of trails with a single classic track beside a skate track (which apparently is also used for fat biking). The Dunseith trail south of the Adam Lake shelter and the John Lake trail (6K in total) are narrower, so they are only packed for skate skiing and fat biking.
The two maps under the Maps tab (below) are dated 2015 and January 2019. A new map is scheduled to be published sometime in early 2020.
The rustic James Lake cabin, 5.5 km from the Adam Lake trailhead, sleeps ~12 people, is free to stay in, but must be booked with the Boissevain District Office 204-534-2028.
The local ski community has an excellent relationship with the Turtle Mountain Park staff . The trails are consistently well groomed.
