Trailhead
Signal Ridge Trail
The Carrigain is 10.6 miles point to point, starting at Signal Ridge Trail. At AMC book time — half the distance in hours plus 30 minutes per 1,000 ft of climbing — that works out to roughly 5-9 hours. Most parties take longer than book time on rough or above-treeline terrain, in winter, or with a heavy pack.
The Carrigain climbs about 3,263 ft over 10.6 miles — an average of roughly 309 ft of gain per mile. That figure is cumulative ascent across the whole point-to-point, not the difference between the trailhead and the high point.
HikerNerd rates the Carrigain Difficult, scored with the Shenandoah difficulty formula — √(elevation gain × 2 × distance) — applied to its 10.6 miles and 3,263 ft of gain. The score measures physical effort only. Above-treeline exposure, water crossings, and winter conditions can make a moderate-rated route the hardest day of your year, so check current conditions before committing.
The Carrigain summits 1 named peak: Mount Carrigain.
The Carrigain starts at Signal Ridge Trail. Check the trail alerts on this page before you drive — trailhead access and parking in the White Mountains change with closures and construction.
