The Grand Canyon is one of the most iconic and awe-inspiring natural wonders of the United States. Located in northern Arizona and part of the Colorado River system, its brilliant red rocks and canyons attract millions of visitors each year. At 18 miles wide, 277 miles long and over 1 mile deep, the Grand Canyon is a magnificent sight to behold. The Havasupai and Hualapai Tribes consider the canyon their ancestral home and share its cultural and spiritual significance. Numerous hiking trails, Colorado River running routes, ranger-led programs, scenic drives, and four viewpoints are available for visitors to experience the canyon. When planning to visit the Grand Canyon, it is important to be aware of the extreme temperatures that the area experiences and to be prepared for any conditions you may encounter.
