People eager to have some fun at Lake Sammamish State Park – or any Washington state park – can do so for free on Saturday, Sept. 29. The state parks commission is waiving the requirement for a Discover Pass in recognition of National Public Lands Day.

An annual Discover Pass costs $30. A one-day permit to use a state park is $10.

Legislation that created the Discover Pass allows for 12 “free days” a year for people to experience state parks. The final free days will be Nov. 10-12, during the Veteran’s Day holiday weekend.

While the Discover Pass won’t be required on Saturday at a state park, it is still necessary on state-managed recreation lands managed by Washington State Parks, the Washington Department of Fish and Wildlife (DFW) and the Department of Natural Resources (DNR).
