Hiking in Fourth Mountain, Maine: trails, map and practical info

Fourth Mountain rises 2,343 feet (714 meters) above the Maine wilderness as part of the legendary 100-Mile Wilderness, delivering a rewarding climb with genuine backcountry character. Various routes through this area gain 726 meters of elevation and take hikers between 2 hours and 45 minutes for shorter summit approaches to over 8 hours for extended loop options — each offering its own level of commitment and reward. The summit payoff includes sweeping panoramic views over Maine's forested highlands, with Mount Katahdin visible on clear days to the north.

What sets Fourth Mountain apart from other peaks in the region is the combination of real elevation gain and genuine remoteness without requiring a multi-day expedition. You're hiking in the 100-Mile Wilderness, one of the most storied stretches of backcountry in the eastern United States, yet this particular summit sees far less traffic than the more famous peaks nearby. That quieter atmosphere is a big part of the appeal.

Note on trail options: Fourth Mountain is accessed via the Appalachian Trail corridor and offers multiple route combinations, including the "Third and Fourth Mountain" loop and connections to the Chairback Range. Route selection affects both distance and elevation gain significantly.
