Truly Amazing Places To Visit

4. The Grand Canyon, Arizona, USA

The  Grand Canyon is a steep-sided  canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters).

The canyon and adjacent rim are contained within Grand Canyon National Park, the  Kaibab National Forest, Grand Canyon-Parashant National Monument, the  Hualapai Indian Reservation, the  Havasupai Indian Reservation and the  Navajo Nation. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery.

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 while the Colorado Plateau  was  uplifted.
