The Wapack Range, sometimes referred to as the Pack Monadnock Range, is a 20-mile-long (32 km) range of mountains in south-central New Hampshire and adjacent Massachusetts, in the northeastern United States. The range is considered very scenic and rugged with many bare summits and ledges ranging from 1,800 to 2,290 feet. The 22-mile (35 km) Wapack Trail, one of the oldest interstate hiking trails in the United States, traverses it. The Wapack Range is also the northern terminus of the 90-mile (140 km) Midstate Trail.
