Wheelchair accessible restrooms, drinking water, and disabled parking are available in the park. There is a wheelchair accessible fishing dock near Siesta Picnic Area.

Beach wheelchairs, intended to provide a means for wheelchair users to travel across the beach, are available free of charge on a first-come, first-served basis. They require an assistant to push and are not intended to enter the water. To arrange for use of a chair, call the park office at (510) 544-3073. Arrangements will be made to bring the chair out to the beach. It takes approximately 15 minutes to prepare the chair. Staff will give a brief orientation to the chair and arrange a time for the chair to be returned.
