Alameda County Dog Parks

Alameda County has several great dog parks for off leash play. It took many years to get these parks established; see this link for the history of dog parks in Alameda City. This county includes Piedmont, Oakland, Castro Valley, Fremont, Hayward, Union City, and Berkeley. Also, the East Bay Regional Parks allow off leash play at most of their parks in the undeveloped areas for a $2 fee. I have not listed many of these off leash areas; please let me know if you have been to any that are worth listing.
