The scene is the Grand Canyon of Colorado with the numerous traiils run alongsedi it to be able to admire the high walls around it. You can walk along these rocky pathways, but a trekking organzation has now made them accessible for less able on mules. There is nothing new about this because at the beginning of the century the tracks were sometimes used by the mules carrying loads or people. What is new is the perfect tourist organzation that the film illustrates as it accompanies the visitors in their journey through this superb natural scenery.
