Acadia National Park — National Park in ME.

By Nicholas Major · Last updated

Acadia National Park is a U.S. National Park Service unit in ME (NPS unit code ACAD), spanning Mount Desert Island, the Schoodic Peninsula, and the boat-only Isle au Haut on the cold-water coast of Down East Maine. The park recorded 4,079,318 recreation visits in 2025 and runs a 5-year mean of 3,992,045 annual visits. The busiest month is August and the quietest is February — winter visits run at less than 2% of August's peak because the Park Loop Road and the other paved park roads typically close to wheels in early December and reopen in mid-April per the NPS Acadia operating-hours page. This page is the navigation anchor for Acadia coverage on this site: the best-time-to-visit pillar covers month-by-month crowd, weather, and access including the Cadillac sunrise vehicle reservation and the Island Explorer free bus; the visitation page covers the long-run annual chart and the 2025 all-time record.

Methodology

Identity, designation, and coordinates come from the official NPS unit page. Annual recreation visits, busiest month, and quietest month are computed from the NPS Visitor Use Statistics Data Package, 2025 on NPS IRMA Stats. This hub does not duplicate the per-month editorial that lives on the best-time page or the year-by-year chart that lives on the visitation page — follow those links for the deep view.
