Today we'll journey from one canyon to the next. We'll finish up today at the big one, the Grand Canyon, but we have a few saucy stop-offs along the way. A meander of the colorado river, which just so happens to be shaped like a horseshoe - Mother Nature, you've outdone yourself with this one! This reservoir is visited by over 2 million people every year, and once you catch it IRL you'll understand exactly why. And now for the one you've been dreaming about (even more than the rest). The star of your USA itinerary. Yup, it's the Grand Canyon. It's about to get extra special too, because tonight we'll be marvelling at the sunset from the South Rim. Charge your phone, clear space on your camera, and prepare to weep.
