One of the Seven Natural Wonders of the World
The Grand Canyon is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is 277 miles long, up to 18 miles wide and attains a depth of over a mile. Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock.
Our guided tours provide comprehensive access to this natural wonder, from rim walks with stunning viewpoints to adventurous hikes into the canyon itself. Experience the grandeur and scale of one of the most spectacular examples of erosion anywhere in the world.
The Grand Canyon's exposed rock layers reveal a spectacular cross-section of geological time, from the 2-billion-year-old Vishnu Schist at the bottom to the 270-million-year-old Kaibab Limestone at the rim. Our certified geological guides explain the fascinating story of how the canyon formed and point out the unique features that make this one of the most studied geological landscapes on Earth.
