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.
