Day-use entrance fees will be waived Sunday at Olympic National Park and state parks to recognize the 103rd anniversary of the National Park Service.

On Aug. 25, 1916, President Woodrow Wilson signed the act that created the National Park Service.

Olympic National Park’s regular entrance fee is $30 per car and $25 per motorcycle.

On fee-free days, other park fees, including wilderness camping and campground fees, will remain in effect. The Olympic National Park annual pass costs $55.

On Sunday, no Discover Pass will be needed to visit state parks, which on the North Olympic Peninsula are Bogachiel near Forks, Dosewallips near Brinnon, Fort Flagler on Marrowstone Island, Fort Townsend and Fort Worden in Port Townsend, Anderson Lake State Park near Chimacum and Sequim Bay near Sequim.

The Discover Pass is a $30 annual or $10 one-day permit required on recreation lands managed by State Parks, the state Department of Fish and Wildlife, and the state Department of Natural Resources.

The free days apply only at state parks; the Discover Pass is still required on Fish and Wildlife and DNR lands.

Free days apply only to day use, not to overnight stays or facilities.

Free days for the rest of the year will be Sept. 28 for National Public Lands Day and Nov. 11 for Veterans Day in both national and state parks. State parks only will offer free entrance on Nov. 29 for Autumn Day.
