Any suggestions on where to obtain a map of the campground to choose a camping spot?
I've not seen a map of individual sites anywhere at this point. I have made reservations at this campground for our stay in July. Reservations can only be made by phone. I was not given a site number. It may be our reservation will simply hold us a spot in the campground and the site will be assigned when we arrive.
If I find detailed maps sometime in the future, I'll try to remember to provide a link here.

Found this link. It at least maps out loops. It states here that sites will be assigned by the Ranger.
