This park is a must if you want to take the Grand Canyon train into the park. We stayed here as part of a RV/train ride package. The RV park is across the street from the train depot and the hotel. The hotel's amenities are available to those who stay in the RV park. Sites were very clean and mostly level. An additional plus is the on site kennel - we boarded our dog for the three days we were in town at a reasonable cost. There were one or two freight trains that came through each night - probably the only negative about the park. The park has free cable and Wi-Fi, a playground for my three boys, and basketball, horseshoes, and volleyball. We would definitely stay here again.
This is a good spot for trips into Yosemite, although there is a good 45-60 minute drive to the valley. The campground was clean, same for the red dirt that covered our spot. We had a spot within eyesight of the bathrooms (where one of the WiFi antennas was located) and WiFi worked well. With a small petting zoo and a hay ride on most nights, my kids were entertained. We would stay here again.
We have found that many of the Riverside County Parks are very clean and well suited for camping: Rancho Jurupa was not an exception. There is a day use area to the park, and there is a campground. The campground was clean and the spots were relatively big. We had a pull-through site with water and electricity only (the full hookup spots were already reserved). We were here for three days and the winds blew hard on the last day. The only reasons I did not give it a 10 out of 10 was the sewer issue. Had to take a portable tank to the dump station a couple of times. And, according to another camper, the lake was stocked on Thursday and fished out by the next day. Would be better to have it stocked before the weekend and limit access to allow campers to get a shot. Otherwise, we will definitely return and book early to get a full-hook up spot.
This is a reasonable choice for those who want to be close to Disneyland. The park was clean and well kept and the management was friendly. The bath / showers were very clean. The park is next to a school, but that did have any effect on our stay. There are apparently some permanent residences in the back part of the park, but again, no problems. We really did not spend much time in the park itself as we were at Disneyland for two solid days. What we did see and experience at the park was good. Be careful when arriving - we missed the obscure street sign and found ourselves trying to get turned around in a nearby residential area.
