OLYMPIA — The Washington State Parks and Recreation Commission is offering a free day in all state parks Saturday in recognition of National Public Lands Day. Day-use visitors will not need a Discover Pass to visit the parks. Free days apply only to day-use access by vehicle, not overnight stays or rented facilities.

Saturday marks the 23rd anniversary of National Public Lands Day — the nation’s largest single-day volunteer effort for public lands.

State Parks free days are in keeping with legislation that created the Discover Pass, a $30 annual or $10 one-day permit required on lands managed by Washington State Parks and the Washington departments of Natural Resources (DNR) and Fish &Wildlife (WDFW).

The Discover Pass legislation provided that State Parks could designate up to 12 free days each year when the pass would not be required to visit state parks. The Discover Pass is still required to access lands managed by WDFW and DNR on these days.

Washington State Parks will have one more free day in 2016: Friday, Nov. 11, in honor of Veterans Day.
