Ditto on the No Reservations - First Come Fist Serve answers.

Nope, it's first come first serve. They don't take reservations at all. But they do have a camp host, so once you get there someone will come say hello and write down that you are there. You can stay up to 14 days at a time, and 30 days total in a year. Hope that helps.

They don't take reservations. First come, first serve. When I was there it was pretty deserted, but the temperatures were in the teens, so.
