Miller State Park

Miller State Park is the oldest state-run park in New Hampshire, a state in the New England portion of the United States. It is mostly located in Peterborough, New Hampshire.

The park is centered on the 2,290-foot mountain Pack Monadnock. Unusually for mountains in this region, Pack Monadnock ("pack" comes from an Indian word meaning "little" and is a reference to nearby Mount Monadnock) has a paved auto road to the top. The mountain is the former site of two hotels, and has a now-unusued fire tower at the summit.

The 533-acre park began in 1891 when three acres atop Pack Monadnock were donated to New Hampshire. It has expanded over the years with many donations and land purchases. Until 1901, according to the state, cattle were driven by foot from Massachusetts farms for summer grazing on open pasture extending nearly to the summit. Virtually all the pastures are now overgrown with forest, as little farming is done in the region.

The park is named after General James Miller, a hero in the War of 1812.

The park is popular with hikers. The Wapack Trail runs through it, crossing Pack Monadnock.
