We’ve been fortunate enough to have visited two of the world’s deepest canyons this year. First was Colca Canyon in Southern Peru back in early July and now Grand Canyon (pics) in Northern Arizona. Some of the signage at Grand Canyon says something like: “Grand Canyon may not be the deepest or the widest but most people agree that it is the grandest.” Couldn’t say it better. Also, Grand Canyon is much more accessible than Colca Canyon. You can explore on various hiking paths on foot or on mule and you can view the canyon along the southern rim on foot, bicycle, car or free shuttle bus.
