This is a cool artsy touristy spot. These colored rocks will only be here for a while longer. So, come get your photo ops.
Depending on the time and day you go, there may or may not be a crowd. I went towards the evening and there wasn't too many people. I was able to see the magic from all angles and even touch/climb them. There are "models" and others doing music videos when I was there. Your shoes will get dusty out there and there are no restrooms.
There is information there to learn about the artist and the rocks.
It was a good rest stop to/from Vegas to get a cool once in a lifetime photo and experience which won't be here much longer.
