Mayo Gulch

Mayo Gulch is a hard, 10.6-mile out-and-back hike in the Superior Ranger District of Montana's Lolo National Forest. The route climbs from a start elevation of about 5,860 feet to a high point of roughly 5,886 feet, then descends back to the trailhead. That makes the total gain and loss about 5,950 feet each way. The steepest stretch comes at about 4.2 miles, where the grade reaches 36 percent. The trail is natural-surface and open to bikes, and it sits on land managed by the Forest Service. The hike is year-round, and a trip should take about 6.5 hours. Summer is the most comfortable time to go. A nearby weather station at a similar elevation records typical July and August highs around 70°F with only about six wet days a month, while winter months typically stay near freezing. Flat Rock Creek and Boyd Mountain are both within about 3 miles. Cabin City Campground is roughly 5 miles away, and Twelvemile Creek, a canoeing route, is about 5.4 miles off.
