There was abundant firewood for purchase at the gate. There is a nice bathroom with flushing toilets and sinks with soap closer to spot #41, but we were at #19, so it was a small walk to get there. However, there was a portopotty right near our site if the walk is too inconvenient.
Our site was flat, and it was easy ground for stakes. Although keep an eye out for critter holes. Tons of little animals hanging out (rabbits, birds, chipmunks). Those chipmunks will definitely go for your stuff if you don't pack it away.
We did see that someone had to be rescued from the riverbed while we were there, so be careful if you plan to climb down into it.
The only bummer was that in some cases, you had to drive to get to other trails, or walk on the road.
