The Thynne Mountain Snowmobile Trails are a groomed and signed trail system maintained by the Merritt Snowmobile Club, accessed from a staging area and parking lot near the community of Brookmere at the start of the Thynne Mountain Forest Service Road.

The trails climb up onto Thynne Mountain via the forest service road, offering riders an extensive network with fees in place to support upkeep.

Two club-maintained shelters are located along the route: the Tin Shed and the Andy's Lake Emergency Shelter, situated on the north shore of Andy's Lake. Riders are encouraged to respect these facilities and pack out all garbage.

The area is based out of Merritt, British Columbia, a community well known for its strong snowmobiling culture and outdoor recreation opportunities.
