12.4 Miles Hard
The Livermore Trail Loop in the White Mountains of New Hampshire is a difficult 12.4 mile loop hike that spans the Livermore Road Trail and Irene's Path to form the loop. The trail begins on the Kangamangus Highway directly across from Lily Pond. It ascends 3 miles up to the tree covered Livermore Pass. After about 2 miles, hike past a small campsite, then past Irene's Path trail head. Livermore Trail then becomes a dirt road. Descend the trail, passing Norway Rapids. Then ascend Irene's Path about 2 miles, pass The Flume, then another 2 mile ascent back to Livermore Trail. It's about a 3 mile descent back to the highway.
This trail is best in the late spring or early autumn when there's no snow; however, this trail can be completed during the winter if you bring snowshoes and possibly crampons. The white mountains in the winter are not easy to hike in the multiple feet of snow-pack.
