Devils Tower is a massive, butte-like rock formation located in northeastern Wyoming, United States. It is considered a sacred site by several Native American tribes, who have used it for religious and cultural ceremonies for centuries. It was declared the first U.S. National Monument by President Theodore Roosevelt in 1906.

Devils Tower rises nearly 900 feet from its base and is over 5,000 feet above sea level. It is made of solidified magma and is a popular destination for rock climbers, who come from all over the world to challenge its steep, vertical walls.

Visitors to Devils Tower can also hike the 1.3-mile Tower Trail that circles the base of the formation and enjoy the surrounding park's scenic beauty. The area surrounding Devils Tower is rich with wildlife, including pronghorns, bighorn sheep, and a variety of bird species.
