We enjoyed our HUMMER Tour to the Grand Canyon. Easy to find right outside the Park entrance. Nice facility. Good parking. Excellent staff and our tour guide Kelly was great !! As a former teacher she sincerely shares great info about the Canyon, the wildlife, the rocks and assorted locations. Very friendly and attentive. We have done assorted tours and this is UP there as a Great One. It was smooth to get into the Park, see the beautiful sites and have bushes identified, animals spotted, and learn interesting facts that you wouldn't learn on your own. Only advise is-sit in the upper seats- the front window is HIGH and front seats can't see out the front !! Thanks again Kelly -was an informative and fun tour. !!!
