Clean, convenient, well-laid out, small sites, and friendly personnel. Back-in spots are cheaper. Wi-Fi is available which means you pay through the nose for it. It's availability is spotty - best closest to the pool area. This is a noisy park. It sounded as if we were in the middle of a major urban area - hey, we were! Sirens, choppers, motor cycles, etc. at all hours. We were so tired though it didn't matter.
This is a great county park. Close to CA-60 and I-215. Use the Roubidoux Blvd Exit off of CA-60. There are two fishing lakes, a nice playground, and well-kept grounds. Some sites are a bit crowded but are level and include a picnic table. This a gated park that we felt totally safe in. There are a lot of birds in this area if you are a birder. It is a Passport America park so we actually only paid $9/night. A super bargain for such quality. Reserve in advance.
