The Grand Canyon was carved out by the Colorado River in northern Arizona in the United States. The northeast end of the Grand Canyon starts at Lake Powell and the city of Page at the Utah-Arizona border. The western end of the Grand Canyon is where the Colorado River empties into Lake Mead at the Arizona-Nevada border.
The North and the South Rims of the Grand Canyon
The Grand Canyon is about a mile deep and separates the Grand Canyon area into the North Rim and the South Rim. In general though, when people mention the rims, they are talking about the national park villages on the eastern part of the canyon that are developed with overlooks and hotels by the National Park Service.

There are no bridges for vehicles going from the North Rim to the South Rim. It is about a five-hour drive to get from the North Rim Village to the South Rim Village.
Indian Nations at the Grand Canyon
Most of the Grand Canyon lies within Grand Canyon National Park and is managed by the National Park Service. Some areas bordering the Grand Canyon rims are owned by Native Nations. The Navajo Indian Reservation including Monument Valley is on the east end. The Havasupai Indian Reservation including its famous waterfalls is on the south-central side of the Grand Canyon. And the Hualapai Indian Reservation is on the southwest side of the Grand Canyon, commonly referred to as "Grand Canyon West" or the "West Rim." The glass bridge called the Grand Canyon Skywalk is not in the national park, rather it is in Grand Canyon West.
You will get a park map when you enter the park at one of the entrance stations. But if you want to get a lay of the land with detailed trails and so on, Trails Illustrated makes three different Grand Canyon maps, depending on where you want to explore. You can buy them on REI.com.
