Jericho Mountain State Park is New Hampshire's dedicated OHV park — the only state-managed off-road riding facility in the state — located in the north country near Berlin in Coos County, roughly 20 miles south of the Quebec border and 100 miles north of Concord. The 4,000-acre park sits in the Connecticut Lakes–Androscoggin highlands and was developed by the state specifically to provide a legal, managed OHV destination to reduce trail proliferation on surrounding public lands. The result is one of the more thoughtfully designed OHV systems in the Northeast: about 100 miles of signed trails covering a wide range of terrain and difficulty ratings, with dedicated beginner loops that keep novice riders away from the more technical ridge and rock routes. Terrain is classic White Mountains north country: steep rock faces, boulder gardens, exposed ridgeline with views, wet bottomland with hardwood and conifer forest, and stream crossings in the valley corridors. The park is accessed from the Jericho Lake Day Use Area on Jericho Lake Road off NH Route 110, where a large paved parking lot with staging area, restrooms, a warming hut, and a trail map kiosk serve as the primary hub. ATVs, UTVs, off-highway motorcycles, and 4x4 jeeps are all permitted on appropriate routes; maps indicate which vehicle classes are permitted on each trail segment. A New Hampshire OHV permit is required for all machines; non-resident permits are available online and at the park entrance. The park is open May 1 through November 30 and is one of New England's most-visited OHV destinations.
