I liked the Grand Canyon - even from the top. I did not realise that you had to book ahead of time in order to go into the Canyon. At the time that I went, there was a 3 week waiting period to go down as they were only allowing a certain number down each day. Perhaps things have changed, but you should check it out to avoid disappointment. I have seen pictures of a skywalk that's over the Canyon now. That may be worthwhile. I also enjoyed the Navajo crafts, weaving and jewellery.
