About Hedgehog Mountain

Hedgehog Mountain is a summit of 2,530 feet in the Saco Ranger District of White Mountain National Forest in New Hampshire, about 8 miles from the town of Bartlett. Summer is the most comfortable time to go. Typical July averages from a nearby weather station run to a high of 77°F and a low of 54°F, and that station sits well below the summit, so temperatures up top run cooler. The closest neighbor is the Mt. Hedgehog East Ledges climbing area, about 0.3 miles away. The Passaconaway Cutoff and Oliverian Brook Trail are both within about a mile, and the Passaconaway campground is about 1.6 miles off.
