Can't remember park rate, may be wrong. We stayed two nights during March 2010 in a 24 foot RV. Some of the sites look pretty small, but backing in, we were surprised just how many big sized RVs actually fit. There was a spot for at least the one big rig we saw here (first site just as you pull in), but I'm doubting they would've fit elsewhere. There was a community water spicket every couple of sites or so. I know people filled up their tanks, but I'm sure you are not actually allowed to stay connected. There's a dump station on the way out. The sites are clean, open, and on pavement, surrounded by wild grass. Ours was fairly level, others looked pretty sloped. The website clearly said NO campfires, but I guess their policy is that you actually can have a small fire if the fire danger is low. You just won't know what the danger is until you arrive. Same with your campsite, you are assigned a site when you arrive, even if you reserved a specific site. We had #59 and it was very nice; we thought, one of the nicest for the time of year. Backed amongst the hills would've otherwise been the nicest, but it created too much shade for the cold weather that we had that weekend. Before we even got out of our RV, we had already seen three deer so that was pretty cool. We continued to see them grazing in the various meadows and the people next to us also saw a pack of coyotes by our sites. There are tons of trails to take all right from the campground. The most notable trail probably being the one to Rock Pool. It's right across the bridge from the Nature/Visitor's Center (which I believe is only open at noon on Sat, Sun), which was a good spot to visit and learn about the area and even watch a little video on the film (and M*A*S*H) history. BTW, the walk/bikeride to both of those locations was a leisurely stroll along a fireroad. The Pool itself was nice to look at, but no one was swimming in it from what we saw. It was much too cold and a little yucky/murky looking for our taste. Also a FYI: if you are on your way to Rock Pool and you start ascending up a little hill and making a few turns, you've past the trail to the Rock Pool, but if you continue on, you'll find Century Lake. (We had to get off our bikes and walk it; not actual bicyclists, just people who like to ride bikes sometimes.) The trail is off to the left, just as the ascent seizes and the trail just reads "No Bikes Allowed". Follow that down a nice shaded path about 200 feet. There were a group of guys there that said they were fishing for Talapia. (For the Rock Pool, there was a sign/marker that said "Rock Pool" and when we went, the sign was just a few feet from an outhouse in an opening along the creek, again, opposite side of the Nature Center (which looks like a white house). Lots of good rock climbing back there and also a good amount of people, but certainly worth visiting if you happen to be in the area. Although, if I was traveling through from another area, I'm not sure I'd go out of my way to see it. (We made the trip from Riverside; about 1 1/2 hours away. Three hours in traffic. Ugh!) There are lots of other gorgeous areas in the Los Angeles and San Bernardino Mountains that aren't as heavily visited. The true beauty of this one, in my opinion, is the fact that it is such an oasis amongst the sprawling Los Angeles metropolis. For that, it is a very special place. We camped here in a Motorhome.
