The community is invited to the grand opening of the $1.1 million all-access playground at 11 a.m. Oct. 15 at Lake Sammamish State Park.

Donors will be recognized as a boulder is unveiled, listing all who donated $1,000 or more to the project.

The first 50 children who arrive (ages 4-10) will be given souvenir scissors to help cut the ribbon, and then it’s play time.

The 8-foot-tall blue heron will greet visitors to the playground plaza. A sidewalk with frequent park benches surrounds the site. Rubber surfacing ensures accessibility for all, from strollers to wheelchairs.

The playground is designed for ages 2-12. The youngest ones will enjoy climbing up the toadstools into the mushroom house before they slide out the other side. Nearby is a mountain to climb, or explore inside the Issaquah Mining Co. coal mine to discover nuggets.

Ready to be challenged? Climb to the top of the 17-foot geodesic dome climbing net, or take a twirl on the rotating net. Next up — the zip line.

There are swings for all ages and twin towers with more slides. Talk to a friend through the talking tubes, or make music on the giant chimes. Take time to learn all about mushrooms and search for hidden animals among the play structures. Bring your own checkers to challenge someone to a game.

The grand opening emcee will be KWRM radio personalities. Refreshments will be served.

The playground came to life through the work of the nonprofit Friends of Lake Sammamish State Park, many local donors and volunteers, and Washington State Parks and Recreation Commission.

The grand opening event is free, but those arriving by car must have an annual Discover Pass or pay a $10 per vehicle day fee.

The park is located at 2000 NW Sammamish Road, Issaquah.
