Gap Mountain Reservation



Gap Mountain is so-named for a prominent saddle or “gap” between its twin summits as seen from the west in Troy. The key attractions at Gap are the stunning vista of Mt. Monadnock looming just to the north and the summer high- and low-bush blueberry crops ringing the open ledges of the north summit. Volunteer land stewards from the Forest Society periodically maintain the openings along the upper reaches of the trail to help sustain the blueberries.

The forest on Gap Mountain is a legacy of extensive farm pastures which formerly extended over the entire mountain, including the 1,862 foot summit. Today, the lower slopes of Gap Mountain are cloaked in second-growth forest of white pine and red oak. The remains of a former apple orchard can be found along the excellent hiking trail from the Jaffrey trailhead on the east, which crosses the historic stonewall-lined Gap Mountain Road. Gap Mountain Reservation is leased to the State of NH and is managed as part of Monadnock State Park.
