Sunset Beach is the largest of the two beaches at Lake Sammamish State Park, located on Seattle’s Eastside.
This beautiful beach is a sand/pebble mix, and is a popular swimming beach in summer (but no lifeguards). Bring an umbrella and beach toys, and enjoy a day looking out over the sparkling waters of Lake Sammamish.
There’s also a seasonal kiosk directly behind Sunset Beach, serving snacks, ice-cream and drinks. This is part of a modern complex that also houses restrooms and change rooms.
One of the best parts of Sunset Beach is the incredible 10,000 square foot adventure playground directly behind it!
