(Strenuous hiking, 1.0 miles one-way)
Acadia Mountain rises dramatically above the west shore of Somes Sound, the only natural fiord on the east coast of the United States. From the open ledges of the mountaintop, broad views of Mount Desert Island and Acadia National Park are possible. Sargent Drive and Norumbega Mountain are just across Somes Sound, while a jumble of mountain peaks and ridges lay beyond, including Cadillac Mountain, the highest point in the park. Just to the southeast are the rooftops of pretty Northeast Harbor.
Trailhead parking for Acadia Mountain is located on the west side of Route 102, about three miles south of its intersection with Route 198 in Somesville, and three miles north of Southwest Harbor. The Island Explorer shuttle bus serves this and many other trailheads on the west side of Mount Desert Island.
The Acadia Mountain Trail starts across the road as a set of granite steps. Just beyond, the St. Sauveur Trail diverges right. Turn left to stay on the Acadia Mountain Trail and meander through a forest of pines and spruce trees. Cross an old fire road, then climb steadily on rock ledges and stone staircases to reach an outlook with views to the south and west that take in scenic Echo Lake, the steep cliffs of Beech Mountain, and St. Sauveur Mountain. A little under a mile from the trailhead, the path finally tops out on the impressive 681-foot summit of Acadia Mountain.
