Olympic National Park — National Park in WA.

By Nicholas Major · Last updated

Olympic National Park is a U.S. National Park Service unit in WA (NPS unit code OLYM), one of three U.S. National Parks that span three distinct landscapes — Pacific coast, temperate rainforest, and Hurricane Ridge alpine — each running on a different operating calendar. The park recorded 3,584,187 recreation visits in 2025 and runs a 5-year mean of 3,080,172 annual visits. The busiest month is August and the quietest is January — winter visits run at roughly 13% of August's peak because Hurricane Ridge Road drops to a Friday-through-Sunday plus holiday Monday schedule with chains required from November through April per NPS. US-101 and the rainforest valley spurs stay open year-round. This page is the navigation anchor for Olympic coverage on this site: the best-time-to-visit pillar covers month-by-month crowd, weather, and access across all three landscapes including the Hurricane Ridge winter schedule and the Hoh Campground reservation window; the visitation page covers the long-run annual chart through the 2024 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.
