New Hampshire trails · Gulfside Trail
A 5.0-mile out-and-back in New Hampshire, with 1,153 ft of climbing. Reaches Adams Five and other lake/pass/summit destinations. Managed by Appalachian Trail.
The climbing leans toward the final third: 47% of the ascent falls between mile 3.3 and mile 5.0. It gives back about 993 ft along the way, so it rolls rather than climbing steadily.
