Nice parks around Riverside, San Bernardino?

Another approach is to be dynamic and plan as you drive. Among other things we have 3 smart phone apps.
1. Trailer Life
2. Woodall's
3. AllStays

All 3 should help. AllStays leads the pack IMHO. There is also rvreviews.com.

Retired from Temecula. Stay at Pechanga. Lake Skinner does have a nice campground, but is well known for locals partying on weekends. Same with Lake Perris. No enforcement of quiet hours. Hemet has some, but the crime rate has skyrocketed recently. If you want to push it and go over Cajon Pass to the Apple Valley/Hesperia area, Desert Willow is not bad. Especially if you are coming from Chula Vista RV resort, you'll appreciate Pechanga. What ever you do, get past Escondido before the afternoon commute back into IE. Traffic is horrible!

Thank you all so very much!

Rancho Jurupa gets our vote. It is a county park and a passport america park. There are two sections; the oldest part has dirt pads and mature trees. The newer section (away from the lake) has concrete pads, FHUs and the sites are really, really wide. In addition to the fishing lake, they also have a water feature for the kiddies and a putt, putt golf course within the park as well as paved walking trails. We have stayed there multiple times;always in the new section; especially when have work done on our rig at the Camping World in San Bernardino.

It is close to the Mission Inn in the old downtown area.

Do contact them before you make reservation just as a precaution. This week the Jurupa Valley did have wildland fire issues.

Good luck

Check out the Mission Inn downtown Riverside. Very cool old building.

Pechanga Rv Resort and casino is a nice place, it's near Riverside in Temecula.

I've stayed at both Jurupa and Skinner. Both very good parks! Bring a fishing pole at either!

We will look them up. Thank you both for you kindnesses.

Never actually camped in the area, but here's a 03/25/13 Post on the Subject.

March Air Force Base (Riverside) has a FamCamp, if you qualify to use them. Such as Retired Military. It's an Air Force Reserve Base. :C March FamCamp seems to offer all you are asking @ $17 a night.

Just found this: Rancho Jurupa Park - A Riverside County Park

Several Riverside County Parks with camping it seems. Park Descriptions I didn't realize how large Riverside County is. All the way to Blythe, Wow.

Might be the only one for you: "Rancho Jurupa Park is situated along the Santa Ana River and is located near charming downtown Riverside just seven miles South of Mission Boulevard on Crestmore Road. Flourishing cottonwood trees, gorgeous meadows, and two lovely 3-acre lakes surround this beautiful park."

However, Lake Skinner Rec't Area might work as well. "Nestled in the hills of Winchester, Lake Skinner is only a few miles east of the Temecula Wineries and within easy access of Interstates 15 and 215." Oophs, After looking at a map, not so close to Riverside at all.

Good Luck with your Quest of Returning to Yellowstone.
