Join us at Cull Canyon, a sand-bottomed swimming lagoon in Castro Valley.   We will be there from 11a-3pm, so feel free to join us for part or all of the day!  For pre-swimmers, there is a large shallow area with beach entry.  Older kids can swim to a large floating dock and jump off!  Register here.

Cost is $4 adults for adults, $2 for children age 1-15, kids under 1 are free.  They only accept cash or check.   Note: if you have an East Bay Parks and Recreation pass, the cost is free.
