Maine's third-highest peak via the AT through Grafton Notch — a sustained 3,000-foot climb rewarded with a fire tower and sweeping views of the Mahoosucs.
Old Speck Mountain stands at 4,170 feet — Maine’s third-highest peak and the endpoint of the notoriously brutal Mahoosuc Range on the Appalachian Trail. The climb from Grafton Notch is straightforward by Mahoosuc standards: a long, steady grind through hardwood and spruce with a restored fire tower waiting at the top.
Why Grafton Notch
Grafton Notch State Park sits on Route 26 in Oxford County, roughly 30 miles north of Bethel. Most visitors stop at the roadside attractions — Screw Auger Falls (not to be confused with Gulf Hagas), Mother Walker Falls, Moose Cave — but the real objective is Old Speck. The AT crosses Route 26 right at the notch, making the trailhead impossible to miss.
The Route
The AT northbound from Grafton Notch climbs the entire 7.6 miles to Old Speck’s summit with no shortcuts and no bail points after the first mile. The trail gains elevation steadily from the start.
Key landmarks:
- 0.0 mi — AT trailhead, Grafton Notch (1,500 ft); park in the large lot off Route 26
- 0.7 mi — Eyebrow Trail junction (short scramble loop — save for the way back)
- 2.0 mi — Hardwood-to-spruce transition; terrain steepens
- 3.5 mi — Old Speck Pond junction and lean-to (0.3 mi side trail to pond)
- 3.8 mi — Summit of Old Speck (4,170 ft); fire tower
The Summit
The restored fire tower at Old Speck’s summit adds 40 feet of elevation and turns a partially wooded summit into a 360-degree panorama. To the north the Mahoosuc Range stretches toward New Hampshire and Goose Eye Mountain. South and east the Oxford Hills roll toward the White Mountains skyline. On a clear day you can pick out Katahdin 100 miles to the northeast.
The summit itself is below treeline — the fire tower is the only way to get the view. Climb it.
Eyebrow Trail Variation
The Eyebrow Trail leaves the AT at 0.7 miles and climbs the cliff face directly above Grafton Notch — exposed ledge with views straight down into the notch. It rejoins the AT at 1.4 miles. Add it to the return leg for variety and a look at the notch from above that you won’t get anywhere else.
Table Rock (Shorter Alternative)
If Old Speck is too much, Table Rock is 1.4 miles from the same trailhead (AT south to Baldpate Trail spur), gaining 1,100 feet to a broad granite ledge with an overhanging cave and excellent notch views. It’s rated Hard for its steepness but takes under 2 hours out and back — a good objective for families with older kids or anyone not up for a 4,000-footer that day.
Logistics
Trailhead: Large paved lot on Route 26 at Grafton Notch. No fee for day hiking — state park day-use fee applies only if using the picnic/swimming areas at the roadside falls.
Old Speck Pond Lean-to: At mile 3.5, it’s an AT shelter with reliable water from the pond. Day hikers often stop here for lunch. Lean-to is MATC-managed, first-come first-served for AT hikers overnighting.
Season: July through October. The summit can accumulate rime ice in October. Snow arrives in November and Old Speck is a legitimate winter objective with microspikes from late November through April.
Dogs: Allowed on leash throughout.
Mahoosuc Context
Old Speck is the southern terminus of the Mahoosuc Range, considered the hardest section of the entire AT. Mahoosuc Notch — a mile-long boulder field just north of Old Speck on the AT — takes most thru-hikers 2–3 hours to cover. Worth knowing if you’re considering continuing north from the summit.
