Antioch & Pittsburg IMHO are the gateway to the beautiful California Delta from the Bay Area, do a Google search for California Delta RV Parks (with Google map), not much in Antioch, but plenty of RV Parks and Marinas near there. We stay in Rio Vista north of Antioch at the Delta Marina & RV Park. If it is just going to be a short visit I would stay at the Fairgrounds in Antioch. When we visit Antioch from Rio Vista we pay a $5.00 bridge toll getting back to Rio Vista on highway 160. The fairgrounds is near some good restaurants including the Red Lobster. Dick
