Washington State Parks is inviting the community to help celebrate the agency’s 108th birthday on Friday, March 19, by enjoying a state park for free.

The free day is the third of 12 State Parks free days in 2021, when visitors are not required to display the Discover Pass for day-use visits to a park.

The free days are in keeping with legislation that created the Discover Pass, which costs $30 for an annual pass or $10 for a one-day pass and is required for vehicle access to state recreation lands managed by Washington State Parks, the Washington Department of Fish and Wildlife and the Department of Natural Resources. The Discover Pass provides daytime access to parks. Overnight visitors in state parks are charged fees for camping and other overnight accommodations; day access is included in the overnight fee.

Remaining free days include Saturday, April 3 (Springtime free day); Thursday, April 22 (Earth Day); Saturday, June 5 (National Trails Day); Saturday, June 12 (National Get Outdoors Day); Sunday, June 13 (Free Fishing Day); Wednesday, Aug. 25 (National Park Service Birthday); Saturday, Sept. 25 (National Public Lands Day); Thursday, Nov. 11 (Veterans Day), and Friday, Nov. 26 (Autumn free day).
