SaveThe Big "M" trail is located of M-55 between Cadillac and Wellston. The trail offers a variety of terrain to challenge every biking and skiing experience level. Most trails are one-way (clock-wise) and should not be biked backwards. The trail is groomed and the parking lot is plowed in winter. There is also a chalet available for skiers.
The trail system was designed in the 1970's by Mr. Cabot, a known cross-country ski trail designer. In the 1960's Big "M" was a downhill ski area. There is evidence of the old T-bar above the current warming shelter.
