The Grand Canyon Back

The northern region of Arizona is dominated by the high deserts and coniferous forests of the Colorado Plateau. In the southwest corner of the plateau lies the phenomenal sight of the Grand Canyon, one of the world's most famous natural wonders.

The mighty Grand Canyon is 446kms long, up to 29kms wide, and attains a maximum depth of 1,857m. The canyon has been formed over the last 5-6 million years from steady erosion of the ground rock due to the flow of the Colorado River and its tributaries - this down-cutting has gradually deepened and widened the canyon, and has exposed almost two billion years of the Eath's geological history!

The area has been inhabited by indigenous people for several thousand years, first seen by Europeans on a Spanish expedition in 1540, and was explored in more detail by various trappers, missionaries and military expeditions during the 19th Century.

In modern times, The Grand Canyon has become one of the USA's must-see highlights and one of the world's most breathtaking natural wonders, attracting a staggering 5 million visitors a year. There are a myriad of incredible viewpoints along its edge, as well as some fantastic trekking trails and opportunities for scenic helicopter flights through the canyon!
