White Mountain National Forest · New Hampshire, Maine
Trailhead Mt. Langdon Trailhead Drive there
This trail has a short spur that veers left to Cave Mountain, and continues to the summit of Mount Parker (1,894 ft.), ending at the Mount Langdon Shelter in 2.9 miles. Please note that this trail goes in and out of the Presidential Range-Dry River Wilderness and all backcountry rules and regulations apply.
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.
