Near San Bernardino, CA

Depends on your needs but if you are an Elks Lodge member, there are several lodges fairly close that could work.

Those are both nice. If you'd like a mountain camping area that is very close, head up to Big Bear Lake, it's only about a 50 min drive from San Bernardino. Don't know when you are planning on going but there is no snow on the ground and it's been in the 50s-60s every day. We have a cabin up there and it's been a very dry year, but that's good if you want to camp right now. Serrano campground is open all year, and is very nice.

I have stayed at both Jurupa and Yucaipa, they are both nice parks with FHU. For Jurupa we have always at the upper loop, further from the lake but nicer sites, in my opinion. If you check out by blog thee should be some pictures and write up on both parks. Enjoy!

Prado is nice but closer is Jurupa a couple others in the area List

I'll assume you mean the city and NOT the county of San Bernadino..

Depending on what area of San Bernardino, which is huge...Pechanga Casino RV Resort...truly 5 star, but a bit far South.
