White Mountain National Forest · New Hampshire, Maine
Trailhead Hubbard Brook Trailhead Drive there
The Hubbard Brook trail is little used, but quickly accesses a beaver pond area that is attractive, although the trail is frequently disrupted by beaver activity. After the wet area the trail descends to the Warren to Woodstock snowmobile trail (also FR 211) and ends at a gate just off NH Rte.118 in Warren at 2.4 miles.
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.
