The Grand Canyon
A mile deep, 277 miles (446km) long and up to 18 miles (29km) wide, the breathtaking grandeur of the Grand Canyon is so impressive that words simply cannot do it justice. One of the great natural wonders of the world, it was formed by the cutting action of the Colorado River over millions of years. The hard rock formations survive as great cliffs, pinnacles and buttes, and the different layers of rock span a range of colours: from purple, fiery-red and pastel-pink, to yellow, brown, grey and soft tones of blue.
Whether by foot or on horseback, from a plane or helicopter, aboard a raft down the mighty Colorado River or by merely gazing in awe from the rim, the canyon's seemingly infinite depths can be experienced in a variety of ways and is a sight not to be missed however one chooses to see it. The park receives hoards of visitors from around the world, who never fail to be transfixed by the sculpted rock shapes, the shifting colours that change with the light, and a tiny glimpse of the Colorado River far below.
The Grand Canyon National Park comprises two separate areas: the South Rim and the more remote North Rim. Separated by the 10-mile (16km) width of the canyon, it is a 215-mile (346km) drive from one Visitor Centre to the other. The South Rim is the most accessible and has more facilities, and as a result it attracts the bulk of visitors to its boundaries. The North Rim is higher in elevation, wetter, with thicker surrounding forests, is further to access, and is cut off by snowfall from October to May. Many people however, prefer its comparative peacefulness and less-crowded lookouts.
Grand Canyon West has recently opened the Grand Canyon Skywalk, a glass-bottomed, horseshoe shaped deck that juts almost 70 feet (21m) from the canyon's rim. It gives visitors the sensation of being suspended amid the canyon's towering red rock walls above a faint sliver of Colorado River flowing 4,000 feet (1,219m) below. There is an additional charge for the Skywalk, which is not for those with a fear of heights. Another great way to tour the Grand Grand Canyon is on the Grand Canyon Railway, a vintage steam train that winds its way around the area.
Both rims have numerous drives and walkways along the edge with various scenic viewpoints, and some hiking trails into the canyon where one can overnight at Phantom Ranch on the canyon floor. The impact of more than four million visitors a year to the South Rim, especially during the busy summer months, is one of overcrowding and traffic congestion; but seeing for oneself one of the most spectacular examples of natural erosion in the world more than makes up for any inconvenience.
There are also several educational and cultural attractions at the Grand Canyon, including the Tusayan Museum and Ruin (near Desert View), the Yavapai Museum of Geology, and the Verkamps Visitors Center.
