Picnicking: Numerous picnic tables and charcoal grills are scattered throughout the park. There are two picnic pavilions that may be reserved up to 11 months in advance for a fee. Unreserved picnic pavilions are free on a first-come, first-served basis. Play equipment is near both picnic pavilions.
Swimming: The sand beach is open from late-May to mid-September, 8 a.m. to sunset. Swim at your own risk. Please read and follow posted rules for swimming.
Beginning in 2015, smoking is prohibited on the beach and in the swimming area. For visitors who smoke and still want to use this beach, designated areas adjacent to the beach are provided. The restriction includes cigarettes, pipes, cigars, e-cigarettes or other handheld, lighted smoking devices.
