Washington State Parks' published statewide camping rate schedule varies by season: Standard sites $23-43/night, Partial-utility (water/electric) sites $35-56/night, Full-utility sites $41-56/night, Primitive sites $12/night flat year-round (peak season is May 15-Sept 15, shoulder Apr 1-May 14 & Sept 16-Oct 31, winter is Nov-Mar). Plus a $10/night extra-vehicle fee and an $8 (online) or $10 (phone) reservation fee, with an additional $15/reservation surcharge for non-residents. A Discover Pass is not required for day-use parking once a camping fee has been paid at that park. (Source: parks.wa.gov/passes-permits/fees.)

Washington State Parks' winter schedule says most parks stay open all year with operational changes in winter, parks with campgrounds may close some sites or turn off water, and many offer first-come, first-served winter camping. Reservations run May 15 to September 15 on washington.goingtocamp.com, the reservable season. Camping from Sept. 16 to May 14 is first-come, first-served in the North Loop campground (sites 1-38). Please note that water may be shut off during these months for winterization. The park is typically winterized by late November and de-winterized by late March. There is a winter water supply in the North Loop. Campground Closes: Partial. Campground Reopens: Open. Loop A closed Sept. 16 - May 14. Loop B open all year. First-come, first-served Sept. 16 - May 14. Water may be turned off. Winter water supply will be near restrooms in Loop B.
