Chestnut Mountain Trail
Chestnut Mountain Trail climbs 2,200 feet in 4.6 miles, past the spectacular Frog Rock pinnacles, to the ridge of Chestnut Mountain. At 1.2 miles, a one-mile spur trail traverses west, providing climbing access and a spectacular hike or bike ride to the base of Frog Rock.
Directions: From Bozeman, drive east on I-90 towards the Bozeman Pass. Take the Trail Creek exit and head east on Trail Creek Rd. Trailhead parking is on the south side of the road, roughly 200 yards from the interstate exit.
