National Parks in New Hampshire.

New Hampshire's NPS network at a glance — units, designations, visit totals, and what shapes the visiting season.

By Nicholas Major · Last updated

New Hampshire has two NPS units — Saint-Gaudens National Historical Park (Cornish, the sculptor Augustus Saint-Gaudens's summer home and studio) and the Appalachian National Scenic Trail's New Hampshire section through the White Mountains. Manchester-Boston Regional (MHT) anchors the southeastern state; Lebanon Municipal (LEB) is closer to Saint-Gaudens. Saint-Gaudens National Historical Park operates Memorial Day through October as the standard window for the historic buildings, gardens, and studio interiors; the grounds are typically open year-round. The Appalachian Trail's NH section is best for thru-hiking June through September given the White Mountain weather; the Presidential Range is the trail's most exposed alpine corridor and weather changes are notorious — check the official Mount Washington Observatory forecast and AT trail page for current conditions before any exposed-ridge hike.

Methodology

Unit list and per-unit visit counts come from the official NPS Visitor Use Statistics Data Package, 2025. The "5-year average visits" column is the mean of 2021-2025 Recreation Visits. Multi-state NPS units (Yellowstone, Death Valley, Great Smoky Mountains and others) are listed under every state they touch; the per-unit visit count is the unit's total, not a per-state share.
