The layered bands of red, orange, and pink rock reveal a rich geological history that captivates visitors from around the world.

The South Rim is the most popular spot for visitors, offering numerous viewpoints such as Mather Point and Hopi Point that provide sweeping vistas of the canyon’s vast expanse. For those seeking a quieter experience, the North Rim offers more solitude and equally stunning views.
