Old Speck Mountain: Maine's Third-Highest Peak and the Mahoosuc Challenge

Old Speck is Maine's third-highest peak, rising to 4,170 feet at the northern end of the rugged Mahoosuc Range. It's a mountain with character—steep trails, a restored fire tower with 360-degree views, and a position at the gateway to some of the toughest hiking on the Appalachian Trail.

Located in Grafton Notch State Park, Old Speck combines with nearby attractions like Screw Auger Falls and Table Rock to make this area a hiking destination in its own right. But the peak itself is the main draw—a challenging climb rewarded with some of the best views in western Maine.

Trail Options

Old Speck Trail (AT)

  • Distance: 7.6 miles round trip
  • Elevation Gain: 2,900 feet
  • Difficulty: Strenuous

The standard route follows the Appalachian Trail from the Grafton Notch parking area. The trail is steep and relentless, gaining elevation steadily through spruce-fir forest. A spur trail leads from the AT to the fire tower at the summit. Expect 5-7 hours for the round trip.

Link to Eyebrow Trail

  • Distance: 8.0 miles loop
  • Elevation Gain: 2,950 feet
  • Difficulty: Strenuous

Add variety by incorporating the Eyebrow Trail, which passes dramatic cliffs with views into Grafton Notch. The loop is slightly longer but adds scenic interest to the descent.

Mahoosuc Trail Connection

Old Speck sits at the north end of the Mahoosuc Range. From the summit, you can continue south on the AT toward Mahoosuc Notch (the famous "toughest mile") and beyond. This is backpacking territory—serious, rugged, and rewarding for prepared hikers.

The Fire Tower

Old Speck's restored fire tower is the highlight of the summit. Climb the steps to the cab for panoramic views:

  • East: The Mahoosuc Range extending toward New Hampshire
  • North: Grafton Notch and the surrounding peaks
  • West: Lake Umbagog and distant Vermont peaks
  • South: The route toward Mahoosuc Notch and the Carter Range

The tower is one of Maine's best-maintained summit structures, offering shelter from wind while you take in the views. On clear days, you can see Mount Washington to the southwest.

Trail Conditions

Old Speck's trails have a reputation for difficulty, and it's well-earned:

  • Steepness: The trail gains 2,900 feet in under 4 miles—that's steep by any standard
  • Roots and rocks: Typical Maine trail conditions with plenty of obstacles
  • Wet sections: The upper mountain retains moisture; expect muddy spots
  • Blowdowns: Remote location means trail crews visit less frequently than in more accessible areas

None of this should deter you—it's manageable for any hiker in reasonable shape. But wear appropriate footwear and expect a workout.

Combining with Grafton Notch Attractions

Grafton Notch State Park offers several other hiking options that pair well with Old Speck:

Screw Auger Falls

A short walk from the parking area leads to this beautiful waterfall cascading through sculpted granite. Perfect for a post-hike cooldown.

Table Rock

  • Distance: 2.4 miles round trip
  • Difficulty: Moderate

A cliff-top overlook with views directly into Grafton Notch. Makes an excellent second hike if you have energy after Old Speck (or a standalone option for a shorter day).

Mother Walker Falls

Another waterfall within the park, accessible by a short trail.
