The pictures show this as a peaceful and tranquil place. I guess once upon a time that was true. Today it is a major tourist attraction and they come by the hundreds to visit this famous slot canyon. Is it worth the visit? Absolutely! However, if you want to take quality pictures then pay the extra money for a specialized photography tour where your guide does crowd control - as the general tours will only allow ceiling pictures that are without people in the way. Since it is very dusty inside you need to commit to one lens only if you have a SLR. These pics are taken with 2 bodies with a 14mm and 21mm focal length.
