People can use any state park for free on Saturday in honor of the system’s 100th birthday, which celebrated the centennial on March 19.

A Discover Pass won’t be required for cars and trucks entering the Washington parks on the free day.

For the anniversary, Cama Beach and Camano Island state parks are planning to host a variety of recreational, cultural and outdoors events.

From 10 a.m. to noon at Camano Island State Park at 2269 S. Lowell Point Road, people can learn to build and fly kites at the Camano Island State Park Kitchen Shelter.

At noon, a hike is planned from the state park to the Cama Center. It’s a moderate trek that covers about 2.5 miles and starts at Lowell Point parking lot near the shelter/bridge. Friendly dogs on leashes are allowed. A free shuttle is available to take participants back to Lowell Point from Cama Center.

At Cama Beach State Park at 1880 S.W. Camano Drive, a cake cutting is planned at 1:30 p.m. with a walk on the beach planned from 2 to 3 p.m. Toy boat building is planned from 10 a.m. to 4 p.m. The boat house and livery is open from 9 a.m. to 5 p.m. And craft projects will be planned from noon to 4 p.m. at the Cama Center.

Also throughout the day, children ages 3 to 14 can create the CamOcean Water Festival Poster Contest. A variety of materials will be available for them to work with.

Another hands-on experience will allow people to “Build-a-Bird” made from yarn pom-poms and feathers.
