I was in the campground on the East side of the reservoir, I'm not sure if there is more than one. There was quite a bit of shade, I'm sure when the cottonwoods are leafed out it would be very shady. The cost was $16 (through April). It was nice, but one of my groups of neighbors were noisy- that seems to be pretty common in park campgrounds though. Next tour I think I will head out in a different direction and try camping somewhere quiet- the park was a great destination for a shakedown tour though.
