Sun Butte is a short out-and-back hike of about 1.4 miles in the Bob Marshall Wilderness, part of the Rocky Mountain Ranger District of the Helena-Lewis and Clark National Forest in Montana. The trail climbs from a low of about 4,817 feet to a high of about 5,600 feet, and the Forest Service lists it as an easy route. It is a natural-surface trail open year-round, and horses are allowed, though it is not accessible. Summer is the most comfortable time to go. Typical averages from a nearby weather station at Gibson Dam, which sits about 1,000 feet below the summit, show July highs near 79°F with lows around 45°F. Winter there is cold, with January highs averaging about 36°F. The closest trail is Sun Butte Cutacross, about 0.2 miles away, and Moose-Furman and Bear Creek are both within a mile.
