There are actually two camp areas. There are two or three small sites at Frank Raines proper. As you turn into the park turn left and on the other side of the old softball field there are a few fire rings in the oak trees. I'm not sure where you go to pay for these but you occasionally see people camping there. There are porta johns in the area but the water is signed as not drinkable so bring your own…. or drive up to the Adobe Spring faucet at the 18 mile mark and fill your water jugs.
Just up the road is the OHV park with a large campground with bathrooms, tables, electrical hook ups, tables, flush toilets and fire rings. Lots of flat spots for rv and trailers and a hall you can rent out for events. It's also a popular OHV area so expect a lot of activity and noise at all times of the day.
Neither spot has drinkable water according to the signage, there is water, but you're not supposed to drink it.
