Appalachian Mountain Club 100 Mile Wilderness Conservation Area The 100-Mile Wilderness is the next-to-last section of the 2,180-mile Appalachian Trail, stretching about 750,000 acres from the village of Monson to Abol Bridge on the West Branch of the Penobscot River south of Baxter State Park. The Appalachian Trail through this region is considered a hard hike covering 92.4 miles with an elevation gain of 15,803 feet. This is considered the most remote stretch of the entire Appalachian Trail, and hikers should be prepared to hike the entire stretch as there are few options to cut the route short. Highlights include tunnels of tight pines, mirror-calm ponds, berry bogs, rushing streams, and craggy ridges. Notable features include Gulf Hagas, known as the Grand Canyon of Maine, which offers views of a rocky gorge with Screw Auger and Buttermilk Falls. Third Mountain offers panoramic views of surrounding mountains and lakes from its summit.
