Make sure you've brought your Discovery Pass. Easily reservable online campsites for tent/car camping as well as RV and group sites. Great for kids, as there is a large playground, beach area, and even a camp store with ice cream (and pretty much anything else you'd need including $4 ketchup). ;) It can get pretty hot in the summer, but when temps soar, book site 108. It's a longer walk to the campsite, but it's right next the river amongst the trees and easily sits at about 10 degrees cooler. (Bring warm sleeping gear for this site.)
