Simply stunning. One should not have to leave this earth without having seen Grand Canyon. It makes you just stare in amazement and wonder. On a more practical note, I went there by train - an original Western railroad from the town of Williams, complete with a bandit holdup. Clichéd maybe, but still fun. The train's schedule gives you just a few hours at the canyon, so maybe you should stay there for the night. Anyway, it will be an unforgettable experience.
