One of the Seven Natural Wonders of the World, the Grand Canyon has some impressive stats to back up that title. Estimated to be around 17 million years old, it runs for some 227 miles and is in places 18 miles wide and more than a mile deep. Oh, and you can see it from space. Big, then.
But this huge hole in the ground slowly carved over many millennia by the constant rub of the Colorado River as it winds its way through Arizona is much more than a geological wonder— it’s a window into history. From the two-billion-year-old rocks it has uncovered, to its holy significance to the Native Americans who’ve lived there for thousands of years, there’s more to do than stand and stare at the awesome views it affords (although they’re reason enough to head there anyway).
So if you’re thinking of taking a trip in the footsteps of our MarkMakers and the other five million tourists who visit it annually, here’s some handy information to keep you away from the crowds.
