Miller State Park is located on the 2,290-foot summit and flank of Pack Monadnock in Peterborough and is the oldest state park in New Hampshire. Three main hiking trails ascend Pack Monadnock to the summit, with the best known being the Wapack Trail; popular routes like Wapack Trail and Marion Davis Trail have a 2.6-mile length with 810 feet of elevation gain. Trails range from moderate difficulty with elevation gains of 810 to 2,170 feet, and a winding 1.3-mile paved road leading to the scenic summit is open seasonally for visitors to drive. The summit features a fire tower, and on clear days views reach to Mount Washington, the skyscrapers of Boston, and the Vermont hills. The views are particularly treasured by birders for the fall hawk migration, where several thousand hawks, eagles and vultures can be seen during September and October.
