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 3,080,171 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.
Designation, states, and coordinates come from the official NPS unit page. Annual visits and the busiest and quietest months are computed from the NPS Visitor Use Statistics Data Package, 2025 on NPS IRMA Stats. Each month's crowd label compares its five-year mean to the park's peak month. Independent site, not affiliated with the National Park Service.
