This tour was amazing! We booked the 730 time slot and ended up being the only group! Our tour guide did a fantastic job providing the history of the canyon, how they maintain it, as well as a bunch of fun facts! On top of it all, she made sure to point out all the great spots for pictures, took a few of our group, and provided me with tips on how to utilize my phone for amazing pictures! I couldn't recommend this tour enough!
