We enjoyed 2 nights here while visiting Six Flags. There are about 4 RV spots, water hookups between the two middle spots but we were able to reach with our hose from our end spot. These are back in spaces. Each lot has a camp grill and picnic table. The only downside to staying here is people come here to walk and can be a pain to get around as there is parallel parking opposite of the RV lots, plus they park on the same side as the RV lots of it's busy. It's supposed to be $12 per night but it's not enforced. Overall, we'd definitely stay here again.
More places need to offer cheap no frills camping. Breath of fresh air for California.
Drove in right after sunset. Note that the park closes at sunset but it seems like you can still drive to and pay for the rv spots after dark. This is nominally an 'enroute' camping spot so it's supposed to be one night only. That said if it's not a busy time of year you could probably stay several nights. Trash and water are provided, so this is a pretty great deal for 12 bucks. Spots are back in and could probably accommodate up to 35 feet.
