Follow 580 to Castro Valley, about 20 minutes from Oakland, and you’ll find the Cull Canyon Recreation Area, including a sand-bottomed swimming lagoon with lifeguards on duty.
My daughter tells me the main thrill is swimming to the far end of the reservoir where a large floating dock allows you to climb up and then jump off into 11-foot deep water.
Make a day of it by reading other things to do with kids in Castro Valley or things to do with kids in San Leandro.

Not warm enough to swim in the 510? Check out the 925 – it’s usually warmer in Antioch where Contra Loma Lagoon offers a similar swimming hole.
