Flooded Trail

Whispering Creek Trail between the foot bridge and the lake trail is flooded and will be closed until further notice.  Updated February 21, 2024.

Don Castro Regional Park is a 101-acre urban oasis on the boundary between Hayward and Castro Valley. The clear blue waters of the swim lagoon are a favorite with central Alameda County residents. The lagoon and adjacent lake were created in 1964 when the Alameda Flood Control and Water Conservation District dammed San Lorenzo Creek.

    To Reach The Park

    Park Accessibility

    Wheelchair accessible restrooms, drinking water, and disabled parking are available in the park.

    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.
