Park is clean, relatively level. Sites are on gravel/dirt; access road is paved. We had a 30 amp back-in site. For our site (85) it seemed the table was on the wrong (hookup) side of the site. Our two young kids liked the playground. We didn't use the pool. Beware if you want to sleep before 9:30 PM on a Friday, the campground is next door to the local high school, and you can hear the football game until 9:30 PM. We camped here since it is near the Oak Glen apple farms that we toured.
We were here April 26, and it was quite hot still. Unfortunately our Rooftop AC decided to fail too. Next year we will try to come in March when they said it is possible to get the wildflowers. The campground is great. Most sites are pull-throughs. Relatively flat too which makes for good bicycle riding for the kids. It said shaded sites are available, but I did not see any unless you count the palm trees. This is typical California High desert. You get a few bushes and cactus and maybe a few palm trees. The visitor center was nice, well done and air conditioned. We didn't get a chance to do any of the hikes. Next time....
This is our second KOA, the first was the San Diego Metro one. This is much different. It is fairly small, only 60 sites. The roads and sites are all dirt/gravel. No grass. Be sure you bring your outdoor carpet. It would be better if they pave the roads and plant grass, but I suppose that would be a lot of irrigation. The kids liked the pool and splash zone and playground. They had movie night on Saturday, free ice cream one night and free pancake breakfast on Labor Day. It is a fairly old campground so the shade trees are fully grown and serving their purpose well. We had site 12, behind the camp store and the trees were so good I really didn't need my awning. Overall a good campground, just be prepared for the dust. Only 30 amps at our site. No cable hookup in site.
Nice RV park. We were on a non-waterfront site. It was quite small. Not enough room to put out our awning. The waterfront sites look much better. Note however, you cannot swim in the lake at the park. You cannot launch or beach a boat from your site at the park if you have a waterfront site. They have rules against bicycling by kids, but everyone does it anyway. If you are using a site, they give you 10% off marina services (boat rentals, etc). No fire pits at the sites. We couldn't have a fire anyway due to the red alert fire danger. If I went back I would try to get a waterfront site, but the temptation of the water and not being able to swim would probably be too much for the kids. Also Wi-Fi showed as three bars, but we were not able to connect to it. I didn't investigate the issue with the office because we didn't need it. We were in site 38. Not far from the office.
