Well worth the long drive with plenty of drive-in spots. Gentle grades to get to the loops. We passed a few hike-in spots on our way to the Aztec Cave that looked great as well. 

Our particular site had a gorgeous view down a valley close to the restrooms. We're told that the restrooms don't usually smell, but the we were there for race weekend, and we ended up packing up a day early to escape the downwind stink.
