We booked a Sunrise Tour and avoided all the crowds. We booked the Sunrise Tour with the option to add time. The area does not open until 7am, however our guide, Yochanan met us at 6am and we headed into the Valley. He took us to locations and spiritual areas not open to the general public. Yochanan, being of the Navajo Nation, was able to take us to these areas. He was very knowledgeable regarding the Valley and shared this with us. He took us to many beautiful areas and patiently stopped wherever we wanted to for picture taking. By getting into the Valley early, we avoided the line of cars on the Loop. We were with Yochanan from 6am until 9:30am. Without hesitation I would recommend the Three Sister Tour group.
