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. Heated yurts and rustic cabins are available year-round. Some units are pet friendly. Campground Closes: Partial. Campground Reopens: Open*. The entire Eastside loop and Westside loop sites 232 - 299 are closed Nov. - May 31. Closure is due to seasonal flooding, dates may change depending on weather. All other sites are first-come, first-served Sept. 15 - May 1. Dump station is closed Nov. - April.
