Mobile home park that is closing and still about 10 old trailers left. But great location two blocks from a very nice beach with a large city playground and $10-$25 less per night than other area RV parks. We camped here in a Travel Trailer.
Having read a review for another Oceanside rv park that mentioned in passing that Catalina was "an armpit" I went there with caution. Maybe not enough. The park is small and hard to maneuver around in. Half the sites are occupied by old mobile homes. Recent rains made some of the sites soft. I got stuck in one and had to get a tow truck to pull me out. After all that I managed to get a site and got hooked up. Utilities were at shared posts. I had to go over a fence to plug in for electricity. There are no restrooms or showers. The laundromat was clean. Most of the neighbors were friendly enough, although the wife heard a lot of screaming from an adjacent condo complex. Only good reason for staying was due to weather and the price. Other RV parks in Oceanside were over $40. Our rate was for Passport America. I would never have paid full rate for this park. If you have a small rig and don't mind the trailer villa atmosphere then give it a try. Just watch out for the wet spots. We camped here in a Motorhome.
