The Washington State Parks and Recreation Commission announced that Monday, Aug. 25 is a “free day.”

Day-use visitors will not need a Discover Pass to visit any parks in the state system.

State parks on Whidbey Island are Deception Pass, Joseph Whidbey, Fort Ebey, Fort Casey and South Whidbey.

The free day is in honor of the birthday of the National Park Service, which was established Aug. 25, 1916.

Washington State Parks will have two more free days this year: Sept. 27, in recognition of National Public Lands Day, and Nov. 11, in recognition of Veterans Day.
