Natural Features and SceneryDiscover the natural beauty where lake meets land—two distinct beaches, Sunset and Tibbetts, offer sandy and pebbly shores that invite you to dip your toes in the cool waters of Lake Sammamish. Explore peaceful boardwalks that wind through wetlands, stroll along paved and unpaved trails that hug the lakeshore and follow babbling creeks, or spread out your blanket beneath towering mature trees in the shade-dappled picnic areas. The park's diverse landscape weaves together meadows, forested pockets, and waterfront vistas, creating countless spots to connect with nature just minutes from the city.
