White Mountain National Forest · New Hampshire, Maine
Trailhead Sugarloaf Trailhead Drive there
This trailhead services the Sugarloaf Trail and Trestle Trail. The double peaks of the Sugarloafs can be ascended via the Sugarloaf Trail in 1.2 miles. The Trestle Trail provides an easy loop along the banks of the Zealand river and then fords the river on over to the Sugarloaf II campground.
The lines are the US Forest Service's National Forest System trails layer (public domain), read 2026-10-16 and simplified for the map; the length is the line's, end to end, and the class, surface, grade and tread width are the forest's own entries where it publishes them - a forest that publishes the centreline alone has none. The trailheads and the points along the way are the Service's recreation points, and the write-ups its own recarea text, unedited. Heights come from USGS 3DEP through Terrain Tiles on AWS (Mapzen/Tilezen), read along each line and rounded; a short trail on steep ground can be off by a few tens of feet. Closures change: check the forest's own site before you go.
