National Parks in Rhode Island.

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

By Nicholas Major · Last updated

Rhode Island has two NPS units — Roger Williams National Memorial (Providence, on the site of Rhode Island's founding) and the Blackstone River Valley National Historical Park (a 50-mile corridor through the cradle of the American Industrial Revolution, shared with Massachusetts) — plus segments of the Washington-Rochambeau Revolutionary Route National Historic Trail. T.F. Green International (PVD) in Warwick is the main anchor airport; Boston Logan (BOS, Massachusetts) is another option for the northern Blackstone units. Both NPS units operate year-round with seasonal interpretive programming and ranger-led walks concentrated in summer. Blackstone Valley includes restored cotton mills and worker-housing districts in Pawtucket, Slatersville, and the Whitin and Slater historic districts; the corridor's 50-mile geography makes it more of a multi-day driving tour than a single-site visit.

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.
