Southwest of Missoula in the Lolo National Forest, the Lolo Pass region with 250 miles of groomed snowmobile trails bridges both the Lolo and Clearwater National Forests high in the Bitterroot Mountains. Dont underestimate the size or the ruggedness of the Bitterroots! The Lolo Pass Winter Sports Area (Idaho Park-n-Ski permit required) is open to snowmobiling from December through March. This heavily forested area provides access to over 200 miles of groomed snowmobile trails at elevations ranging from 3,200 to 6,500 feet. East Fork, Lost Park System, Elk Meadows and Moose Ridge are just some of the trails that lead deep into the heart of the Bitterroot Range, with lots of meadows and play areas along the way.
Overall, Lolo Pass is the 6th most popular snowmobile trail of all 33 snowmobiling rides in Montana.
