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. A winding 1.3-mile paved road leading to the scenic summit is open for visitors to drive in summer and on spring and fall weekends. Three main hiking trails ascend Pack Monadnock to the summit. The best known is the Wapack Trail, which is a 21-mile footpath that extends from Mt. Watatic in Ashburnham, Massachusetts to North Pack Monadnock in Greenfield. It is believed Native Americans named the area's mountains, and that "pack" means little. On clear days views reach to Mount Washington, the skyscrapers of Boston, and the Vermont hills.
