Washington State Parks offers several "free days" when a Discover Pass is not required to visit a state park.
Friday, November 23, 2018, is Autumn Day and a free day to visit Washington state parks.
Please note, free days apply only to day use (not overnight stays or rented facilities). A Discover Pass is still required to access lands managed by the Washington state departments of Natural Resources and Fish & Wildlife on these days.
Sno-Park permits are still required on free days at designated Sno-Parks during the winter season.
