Quite possibly one of my favorite places of all. It's incredibly beautiful and a little overwhelming to take in. If you're driving through in either direction, you will find it very difficult to see everything while trying to pay attention to the road. There are pull offs for many of the major sites/trails/features. However, there are some areas that are by the roadside with no real area to park and see. I'd recommend getting well acquainted with the area on a map and planning what areas you want to stop at before driving through, which might make the drive more pleasant. There are restrooms at certain wayside areas.
