Washington State Parks offers several “free days” when a Discover Pass is
not required to visit a state park. Following are 2015 free days:

April 4: Saturday Spring Day
April 22: Earth Day
May 10: Sunday Spring Day
June 6: National Trails Day
June 13: National Get Outdoors Day
Aug. 25: National Park Service Birthday
Sept. 26: National Public Lands Day
Nov. 11: Veterans Day

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.
