Once settled in, it was a great campground. However, reservations and getting a spot were difficult, with a lot of conflicting information from recreation.gov, the billboard on site, and how things actually work. For B loop, you must use recreation.gov -- no way around it after you get there, no way to adjust. Calling recreation.gov, they say "talk to the people on site." On site, the rangers say "talk to recreation.gov; we have nothing to do with it." The poster at the campground says to call a number for assistance -- the local visitor center. First, it's impossible with cell phone reception, so it's a hike or a shuttle ride to the visitor center (to get the above information). Ugh. Your best bet is to get a site on loop A when you first arrive, and pay at the box. Then go hike somewhere to get cell service to find a spot you really want after personally looking at loop C and B. Loop B, however, has few sites with level pads; most are at quite a tilt. Loop A has better pads. Shade is an issue in the summer -- hard to tell online which are shaded, but loop C has the best chance of shade.
