In celebration of National Public Lands Day, Olympic National Park will waive entrance fees for visitors on Saturday.
Other park fees, including wilderness camping and campground fees, will remain in effect.
Nine federal land management agencies are participating in the free day, along with 125 state, county and city governments.
Olympic National Park charges $10 for a single-visit vehicle pass and $5 for a single-visit individual permit. Both the pass and permit are good for seven days.
