About Lake Sammamish State Park

Boating and waterskiing draw visitors to the south end of Lake Sammamish, where the park stretches across 512 acres and holds nearly 6,858 feet of shoreline. Issaquah Creek flows into the lake within the park boundaries, adding a second waterway to the site. Managed by the Washington State Park System, the property functions primarily as a base for watersport activities on the lake.

Hours, fees, camping, reservations and closures are set by the park and change often. Check the official park site before you go.
