The Grand Canyon is one of the wonders of the world. Its 277 mile length is protected by 1.2 million acres of National Park. The fabulous views of nature"s sculpture are known worldwide - indeed are even better then our wildest imagings. The walking trails are equally awesome. Many are serious endeavours only for the most experienced.The American South West hosts a profusion of national and state parks and wildernesses. It boats a seemingly endless variety of deep canyons, deserts high and low, snow-capped mountains and raging rivers. The Grand Canyon is only the largest of these canyons; the smaller Zion and Bryce Canyons and the National Park are less famous, but lose nothing in comparison.
