The donkey ride down is fun, but f you have the slightest fear of cliffs WOW. Those donkeys walk on a narrow trail with big drop offs, and its hard to get the smell of donkey off your clothes afterwards, but its alot of fun.The veiws are amazing, You'll enjoy the canyon. You should go to Nogales Mexico while in Tucson too, good shopping there. Post some pics when you get back. Rick
