- Marshall Lake trail system now includes three snowshoe trails. Stewart trail loop starts at the beginning of the Mackay trail. Borscht Warrior starts at the west end of the lake off Jolly Jack and Rick’s Not Here starts off Borscht Warrior. Enjoy the hike!! Since operating a trail system has numerous costs, we urge all trail users, including snowshoers, to buy memberships seasonally. Check out the trails on the map page
