Antelope Canyon
This canyon is on LeChee Navajo land near Page Arizona. You can’t go alone and explore by yourself, so you have to take one of the tours offered. The tour is worth the cost. Take the morning tour, so you can see the interesting light effects.
If you wear contact lenses, I’d advise you to take some tight fitting protective glasses. There’s a constant light fall of sand. I was miserable after the first ten minutes.
