Gap Mountain is named for a prominent saddle or “gap” between its twin summits. It is the focal point of a 1,120-acre natural forest preserve featuring a stunning vista of Mt. Monadnock, blueberry bushes on the north summit, and two popular moderate trails that lead to the 1,862 foot north summit, each a little less than 1.5 miles. The south summit is wooded and doesn’t have a view. Both the north and south trails are a segment of the Metacomet-Monadnock Trail, which is a 114-mile trail connecting the Metacomet Ridge of the Pioneer Valley in Massachusetts to Mount Monadnock. Each trailhead has a small parking lot. Portable restrooms are available in the summer months. Leashed dogs are welcomed.
