This was our first trip to the Grand Canyon and were so fortunate to find Canyon Dave's Canyon Tours. Dora ("Mrs. Canyon Dave") has a Biology degree and Park Service background among other things. Dave is a geologist so the trip consists of not only numerous stops at amazing view spots, which we could have done on our own, but also includes lessons and insights into the geology, history, biology, folklore, and Native American culture in the region. We were picked up promptly at our hotel and were whisked away for a full day of learning and sightseeing in a comfortable air conditioned van. They bring snacks, drinks, buy lunch for you at an authentic trading post on a Navajo reservation , provide binoculars, chairs for the geology hands-on lesson. All you need are suitable clothing and your camera, the trip is not physically demanding and is suitable for all ages. Quite frankly I feel if anything ,the services provided are under-priced.
