Mountain Biking Grassy Mountain Loop

*****   Add a review
#15 of 265 mountain bike trails in Montana
#1,555 in the world

The rides starts with a long fire-road climb, stay on the main road to a large grassy meadow. The road descends slightly, take the single track here to the left until you meet an old boggy 4wd road. Continue on this road until you see another single track go right at a small meadow. Follow this single track, top of the climb is about a mile then a great descent. Some steep, rocky, root drops near the top, later many bermed and banked turns. The descent ends after a series of switchbacks at the Brackett Creek Trailhead. Continue south on the paved road about 5 miles to start point.
