The Grand Canyon is one of the world's most famous natural wonders 
and is a favourite attraction to visit for tourists. Before going to 
visit the attraction, it might be an idea to get to know the site a 
little better; why not wow your friends and family or simply other 
tourists with these titbits of information on one of the world's 
greatest natural wonders?
The
 Grand Canyon is Arizona's number 1 tourist attraction. This is not 
particularly surprising considering the widespread fame of the canyon, 
but with places like Monument Valley and the Four Corners monument to 
compete with, the Grand Canyon has surely earned its position at the 
top.
At 277 miles long and up to 18 miles wide it is one of the 
Natural Wonders of the World. The huge gorge is joined on the list by 
other natural wonders such as the Aurora Borealis, Mount Everest and the
 Great Barrier Reef.
Only 10% of visitors enter the North Rim. 
This part of the canyon still gives visitors spectacular views of the 
canyon but the more familiar vistas of the South Rim draw in the larger 
numbers.
The Grand Canyon Skywalk was completed in 2007 at a cost 
of $31 million. This is located on the West Rim and allows visitors to 
walk out on the glass-bottomed platform. The Skywalk does have amazing 
views, but unfortunately cameras are not allowed on it, so some people 
leave the Skywalk feeling disappointed. For the best views of the canyon
 it would be more advisable to take a helicopter ride and perhaps 
incorporate the Skywalk into that trip.
Humans lived in the Grand 
Canyon around 4,000 years ago. Those who have travelled deep into the 
canyon discovered a number of caves, and in these caves were artefacts 
that proved there had been human existence long ago. Animal figurines 
that were a few inches tall were found, and they were made mostly from 
willow or cottonwood twigs.
The canyon is populated by 5 Native 
American tribes: the Hopi, Navajo, Havasupai, Paiute and Hualapai 
tribes. The ancient tribes live around the canyon area and some are 
happy to integrate with tourists, showing visitors all about the history
 of their ancestors and the cultural practices that have been passed 
down through the ages.
