New Hampshire routes span a broad diversity of settings, from well-traveled trails in the White Mountains, to challenging hikes in the Presidentials, to remote logging roads with spectacular views in northern parts of the state.
Each map below displays a topographic map showing a Mountain Birdwatch route; each route has up to six survey stations where observers conduct point counts. The route number is the first number at each point, and the station number occurs after the dash. When two routes are close together, some maps may display more than one route.
