Appalachian Trail: Old Blue and the Bemis Range
Appalachian Trail between South Arm Road (Andover) and Route 17
North of Andover, the Appalachian Trail climbs out of Black Brook Notch onto Old Blue Mountain, crosses Elephant Mountain, and then runs along the open ledges of the Bemis Range before dropping to Route 17 near the Height of Land. It’s a long day or an easy two-day trip with one lean-to near the middle of the range.
A July hiker who posted on Views from the Top described steep, rocky ledges on the climb of Old Blue and called the open ledges on Bemis hot and exhausting in full sun.
The hike
The southern trailhead is on South Arm Road, about 7.6 to 7.7 miles from Route 120 in Andover. Maine Trail Finder says the trail quickly becomes very steep, with iron rungs on the steepest rock faces, then eases through mixed hardwoods with a view over Black Brook Notch before steepening again through spruce-fir forest. Maine by Foot puts the 3,600-foot summit 2.6 miles up, with about 2,170 feet of gain, and describes views over scrubby, stunted spruce rather than an open top. The July Views from the Top hiker found Old Blue’s summit a broad dome with many unmarked paths and advised watching the blazes.
From Old Blue, the AT continues east toward Elephant Mountain. The July hiker passed old-growth spruce and a boggy col with puncheon below Elephant, then reached the Bemis Range, where he described more than four miles of open ledge.
The Bemis Mountain Lean-to sits along the ridge, about 4.5 miles from Route 17 by Maine Trail Finder’s count, with a privy and a fire ring. A May trip report on Views from the Top describes a hiker reaching it at 7 p.m.: “I arrived at the shelter at 7 p.m. and found the last entry in the register was from November.” The July hiker, on a summer weekday, found four people lounging there and expected about 20 young campers that night.
Maine Trail Finder describes the range from the north: from Route 17, the trail crosses Bemis Stream, which splits around a small island, crosses the grade of the old Rumford Falls and Rangeley Lakes Railroad, and climbs over First and Second Peaks to the lean-to. Third Peak and Fourth (West) Peak, the highest in the range, are beyond it. The ridgeline averages about 3,000 feet. The July hiker described the Bemis Stream valley as about 1,000 feet of descent and 800 feet of climbing back to Route 17.
North of Route 17, the AT continues through the Four Ponds area to Route 4. South of South Arm Road, it heads toward the Baldpates and the Grafton Loop Trail.
Tips
- Bring plenty of water on hot days. The July hiker’s advice, after a sun-baked crossing of the Bemis ledges.
- Watch the blazes on Old Blue’s summit, where unmarked paths split off.
- Plan a car shuttle between South Arm Road and Route 17.
- Check the Bemis Stream crossing. Fording may be needed depending on season and weather.
- Expect lingering snow in spring. The May report found up to two feet on Old Blue’s north side, with many blowdowns.
Camping
The Bemis Mountain Lean-to is the overnight stop on this section. Maine Trail Finder says fires are allowed only in its fireplace ring, and that building a fire outside a provided ring is illegal in Maine. The ATC’s Maine rules allow fires only at designated sites and prohibit camping above treeline. When in doubt, camp only at designated shelters and campsites. No permit or fee was found. Trail conditions go to the MATC Baldpate District Overseer (baldpate@matc.org).
Inside Intel: The May Views from the Top report found the Bemis Mountain Lean-to register’s last entry dated the previous November, a sign of how quiet it can be early in the season. In midsummer, the July hiker pumped water there and found it busy. No other camper accounts recommending a site on this section were found.
