The Grand Canyon: Arizona

If Australians boast about the beauty of Outback, Americans are proudly flaunting their Grand Canyon. One of the most awe inspiring features made by nature anywhere in the world, Grand Canyon is a steep gorge cut by Colorado River. Situated within the Grand Canyon National Park, the canyon is 227 miles in length, up to 18 miles in width and nearly 6000 feet deep. It is believed that it took nature nearly 2 billion years to carve this magnificent piece of land. It attracts nearly 5 million visitors every year who apart from sightseeing indulge in whitewater rafting, hiking and sky walking. You can also hire a helicopter and take a tour over the Grand Canyon, a must have experience.
