Washington State Parks offers passes that reduce or waive camping, moorage, watercraft launch fees and day use for limited income senior citizens, disabled veterans, foster parents and people with disabilities. Qualified individuals may apply for more than one type of pass, although only one pass may be used at a time. These passes are valid only at Washington state parks. Please Note: Washington State Parks pass discounts do not apply to yurts, cabins, vacation houses, roofed accommodations, retreat centers or picnic shelters. Pass discounts also do not apply to the extra vehicle fee. The extra vehicle fee is not part of the camping fee and must be paid when checking in at the park.
