National Parks in Connecticut.

Connecticut's NPS network at a glance: units, designations, visit totals, and what shapes the visiting season.

By Nicholas Major · Last updated

Connecticut has two NPS units: Weir Farm National Historical Park in Ridgefield and Coltsville National Historical Park in Hartford. Weir Farm preserves the home and studio of American Impressionist Julian Alden Weir. It's the only NPS unit in the country dedicated to American Impressionism, with the artist's studio open for guided tours and the surrounding pastoral landscape kept open for plein-air painting. Coltsville covers the historic Colt firearms complex and is still being developed; interpretive programming is limited for now. Both units operate year-round with summer the busiest season for interpretive programs. Bradley International (BDL) is the main anchor airport. Neither site carries the 'National Park' title, but both are genuine NPS units worth the 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.
