My two favs are Paradise by the sea at the beach,which is very spendy in the summer, and Guajome County Park on the east side of Oceanside which can be hard to get into. We have stayed at Olive Park and it was very nice and quiet. Yes,some of the sites need pretty good leveling. I got the idea a couple of years ago that they were going to be phasing out the trailer park and adding more rv sites. It's really a good location in the middle of everything. The two local state parks are very hard to get into and are very expensive. If you are an Elk,there is an Elks club in Oceanside with hook ups also.
