Storm-damaged Trails

The Chabot-to-Garin trail is open but storm-damaged. Take extra care and follow all signage on the trails. Updated 1/19/2023.

 

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

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

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 reservoir no longer exists south of the swim area.

To Reach The Park

Attractions

NOTE: No alcohol, glass containers, or portable bbq’s allowed in the swim lagoon area.

There are several reservable picnic areas outside the swim complex. For information, call 1-888-EBPARKS or 1-888-327-2757, press option 2.
It is strongly recommended that visitors make a picnic reservation for Weekends and Holidays. Any group of 30 or more people must make a reservation, any day of the week.

Cull Canyon is also on the Chabot-to-Garin Regional Trail, which is being developed between the two parks. The trail runs along Cull Canyon Rd, starting at Heyer Avenue, and drops down toward Cull Creek, paralleling Alameda County Flood Control property. It continues through Cull Canyon Regional Recreation area then heads north for six miles into East Bay Municipal Utility District property to EBMUD's Chabot Staging Area on Redwood Road (an EBMUD hiking permit is required for this section). From there the Willow View Trail leads into Anthony Chabot Regional Park.
