Use to be before the reservation system that you could go there even late on a Friday in the Summer and get a site EASY. No one used it, since most people prefer to camp within Yosemite. Now with reservation system I think people book it up and never use it. So you don't know what to think. I would forgo getting reservations for the place and just go.

You will probably find a vacant site. Anyway, it is quiet, but you do hear bears rumbling in the night sometimes. I have camped there three times without a problem. Close to Yosemite and only five miles to Rainbow pool. A great place to swim and fish.
