The peak of Belknap Mountain is the highest point in the county. Although of only modest elevation, the isolation of the Belknap Mountains gives Belknap Mountain of relative height above the low ground separating it from the White Mountains, making it one of the fifty most topographically prominent peaks in New England. Belknap Mountain is flanked to the northwest by Gunstock Mountain, the site of the Gunstock Mountain Resort ski area. The summit of Belknap Mountain features an active fire tower.
