Stayed for one night; we arrived at 3 pm and there was only one site open, which we backed into (no pull-throughs).  Water at each site, trash cans and bear-proof containers.  There are also pit toilets, very clean.  Cost is $20, we paid $10 with our parks pass.  There are 10-15 sites, paved, in a small circle, so pretty cramped.  Overall, quite pleasant, lots cooler than the plains below.  Not all the sites are level and some looked difficult to back into, while others were easy.
