5/5 - Excellent
If you don’t mind buses, I suggest parking at the Visitor Center and jumping in one of the free shuttles. It will drop you off at each of the sights along the Loop Rd. Then you can walk as much or as little as you like and get back on. Like the hop on hop off buses the larger cities have! We found parking to be quite a challenge and the only time we saw people nearly lose their cool. A shame when you are in such a beautiful place!
