About The Park

This popular Castro Valley swimming spot is only a short drive north from Interstate 580 on Cull Canyon Road in Castro Valley.

When the swim area was constructed, a secondary dam was built to provide an inner swimming area complete with a sandy beach. Never previously tried, this innovation made the swim area water level independent of the reservoir's, unaffected by summer draw-downs.

The lagoon won the 1966 Governor's Design Award for Exceptional Distinction for Recreational Development in the category of landscape.

Park Activities

There are several reservable picnic areas outside the swim complex. For information, call 1-888-EBPARKS or 1-888-327-2757, press option 2.

Cull Canyon also is on the Chabot-to-Garin Regional Trail, which is being developed between the two parks. The trail runs along the east side of Cull Canyon Reservoir, then heads north for six miles through East Bay Municipal Utility District property to EBMUD's Chabot Staging Area on Redwood Road (an EBMUD hiking permit is required for this section, phone 287-0459). From here the Willow View Trail leads into Anthony Chabot Regional Park.
