Big M Trail

This trail is good for Hiking Biking XC Skiing

The Big "M" trail system offers a variety of terrain to challenge every biking and skiing experience level. Traverse up and down hills as you loop through the woods. The trail is best known for mountain biking. Most of the 25-miles of single track trail are one-way (clock-wise) and should not be biked backwards. The bike trail is open from April to September.

Cross-country skiing is popular during the winter months when 18 miles of trail are groomed and the parking lot is plowed. There is also a chalet available for skiers. Snowfall averages 130 inches from December to March, but the best skiing is usually in January and February. One loop provides several miles of ungroomed trail that is is perfect for snowshoeing.

Although the trail is primarily used by mountain bikers, it is open to hiking. The trail runs near, but is not connected to, the North Country National Scenic Trail for a short stretch. The Marzinski Horseback Riding Trail also crosses the Big M trail at two locations.

The trail system is located off of M-55 between Cadillac and Wellston.
