Morgan and Percival Loop

The Morgan and Percival Loop is 5.0 miles around the loop, starting at Mt Morgan trailhead. At AMC book time (half the distance in hours plus 30 minutes per 1,000 ft of climbing), that works out to roughly 2-5 hours. Most parties take longer than book time on rough or above-treeline terrain, in winter, or with a heavy pack.

The Morgan and Percival Loop climbs about 1,857 ft over 5.0 miles, an average of roughly 371 ft of gain per mile. That figure is cumulative ascent across the whole loop, not the difference between the trailhead and the high point.

HikerNerd rates the Morgan and Percival Loop Moderate on a six-tier scale from Easy to Most demanding. The rating comes from the route itself: its 5.0 miles, 1,857 ft of gain, and the steepest quarter mile of trail, with routes known for scrambles or ledges rated a step harder. It is the same scale our NH 4,000-footer difficulty ranking uses. Above-treeline exposure, water crossings, and winter conditions can still make a well-rated route the hardest day of your year, so check current conditions before committing.
