Trail description

Description

Number Four Mountain rises from Maine's rugged highlands, offering hikers a moderately challenging climb through dense forests to spectacular summit views of Moosehead Lake and the surrounding peaks. This Appalachian Mountain range gem delivers the quintessential Maine hiking experience—thick woodlands, steady climbs, and rewarding panoramic vistas that showcase the state's wilderness character.

The mountain sits in the heart of Maine's backcountry, where the landscape transitions from rolling hills to more dramatic terrain. Unlike some of the state's more popular peaks, Number Four Mountain maintains a quieter atmosphere while still providing the substantial views and satisfying challenge that draw hikers to this region. The trail cuts through classic Maine forest—a mix of hardwoods and conifers that creates excellent habitat for the area's diverse wildlife population.

The Trail Experience

The round-trip hike covers approximately 3.4 miles with a steady ascent that gains 881 meters of elevation, making this a genuinely challenging climb despite its moderate classification. Most hikers complete the journey in 3 to 4 hours, though the pace varies significantly depending on fitness level and how much time you spend enjoying the scenery along the way.

The trail begins in thick forest where the canopy creates a cathedral-like atmosphere, especially during the early morning hours when mist often lingers among the trees. As you climb, the steady upward grade keeps your heart rate elevated without becoming punishingly steep. The path is well-defined but requires attention in places where roots and rocks create natural obstacles.

Wildlife encounters are common throughout the hike. The diverse forest ecosystem supports numerous bird species, making this an excellent destination for birdwatching enthusiasts. Bring binoculars if you're interested in identifying the various species that call these woods home. The dense vegetation also provides cover for larger mammals, though sightings are less predictable.

Photography opportunities abound, not just at the summit but throughout the climb. The interplay of light filtering through the forest canopy creates constantly changing conditions, while seasonal variations in foliage offer dramatically different experiences depending on when you visit.

Summit Views and Rewards

The summit of Number Four Mountain opens up to sweeping panoramic views that justify every step of the climb. Moosehead Lake dominates the vista, its expansive waters reflecting the sky and surrounding mountains in a display that captures the essence of Maine's wilderness. The lake's size and the way it nestles among the forested hills creates a sense of scale that's both humbling and inspiring.

Beyond Moosehead Lake, the surrounding peaks roll away in waves of green, offering a perspective on just how vast and wild this region remains. The summit provides an ideal spot to rest, refuel, and absorb the scenery before beginning the descent. Many hikers find this pause at the top becomes the most memorable part of their day, as the combination of physical accomplishment and natural beauty creates a powerful experience.

The exposed summit can be significantly windier and cooler than the protected forest below, so even on warm days, having an extra layer readily available makes the summit time more comfortable.

Planning Your Visit

Weather conditions in this region change quickly and can vary dramatically between the trailhead and summit. Dressing in layers allows you to adjust as conditions change throughout your hike. The forest provides some protection from wind and precipitation, but the summit exposure means weather impacts are more pronounced at the top.

Sturdy hiking footwear is essential for this trail. The combination of elevation gain, natural obstacles like roots and rocks, and potentially muddy or slippery conditions in places makes good traction and ankle support important for both safety and comfort.

Water requirements are significant given the steady climb and 3-4 hour duration. Carry more than you think you'll need, especially during warmer months. The physical demands of the elevation gain mean you'll be working harder than on flatter terrain, increasing your hydration needs.

Pack substantial snacks or a light meal to enjoy at the summit. The combination of physical exertion and spectacular views makes the summit break particularly satisfying, and having good food enhances the experience while providing necessary fuel for the return journey.

The trail's moderate-to-challenging difficulty makes it suitable for hikers with some experience who are looking to push their limits, as well as seasoned hikers seeking a satisfying workout with excellent payoff. While not a beginner trail, it's accessible to anyone with reasonable fitness and proper preparation.

Number Four Mountain represents Maine hiking at its finest—challenging enough to feel like an accomplishment, beautiful enough to create lasting memories, and wild enough to provide a genuine escape into nature's embrace.

Number Four Mountain delivered an intense hiking experience that truly tested my fitness level. The 881m elevation gain over roughly 3 hours kept my heart pumping throughout, but the summit views across the Maine Highlands made every difficult step worthwhile. This trail is definitely not for casual hikers—come prepared with proper conditioning and gear.

The challenging terrain on Number Four Mountain lives up to its hard difficulty rating. While the steep sections demand significant effort, the remote wilderness setting provides genuine solitude that many hikers seek. Trail markers were helpful navigating the varied landscape, though I wish there had been more water sources along the route.

Solid mountain hike with genuine wilderness character. The 881m elevation gain provides a legitimate challenge that separates casual walkers from serious hikers. The remote Maine Highlands location offers peaceful solitude and undisturbed natural beauty. Trail conditions were generally good, though the steep sections require careful footing and proper hiking boots.
