The Washington State Parks and Recreation Commission is allowing visitors to enjoy their parks at no cost on two days in April.
Visitors will not need to display a Discover Pass on April 4 and April 22, which is Earth Day.
Normally a Discover Pass, which costs $30 annually or $10 for a one-day pass, is required to access state parks.
Other free days in 2015 are May 10, June 6, June 13, Aug. 25, Sept. 26 and Nov. 11
