Extremely tight! I had to maneuver a 25' trailer through there and was nervous the whole way around. I'd avoid summers and weekends especially! I tried to get the last spot with FHU's and on either side were some serious partiers who adopted the vacant spot. They didn't want to move and were a bit aggressive in nature. Remember this is So Cal and MANY campers take it as carte blanche to party pretty heavily. Since you can't reserve an actual spot it's a roll of the dice during popular times. There was only one "ranger" to do check in and 3 of us had to wait for him to fill propane bottles....I headed down to Banning KOA for the week. I did have a great time when I camped there in early May one year. Cold and even snowed but only half full! Partiers don't like cold rain and snow!

Some sites would be easy and others not. It’s a large campground with some very nice sites but most are very close together and not all are level It’s a long windy road up to the campground
