Cedar Breaks National Monument is a U.S. National Monument located in the U.S. state of Utah near Cedar City. Cedar Breaks is a natural amphitheater canyon, stretching across 3 miles (4.8 km), with a depth of over 2,000 feet (610 m). The elevation of the rim of the canyon is over 10,000 feet (3,000 m) above sea level.
The eroded rock of the canyon is similar to formations at Bryce Canyon National Park, but has its own distinct look. Because of its elevation, snow often makes it inaccessible to vehicles from October through May. Its canyon-rim visitor center, tiny compared to the visitor centers at nearby and better-known Bryce Canyon and Zion National Park, is open only from June through October, although park headquarters at a lower elevation in Zion is open the rest of the year. It is not as popular as some of the nearby National Parks, but several hundred thousand people do visit annually. The national monument area is the headwaters of Mammoth Creek, a tributary of the Sevier River.
There are several hiking trails throughout the park, and a campsite near the canyon rim.In 2006, Iron County officials considered a proposal for legislation to expand the monument and rename it Cedar Breaks National Park. The new park would include the adjacent Ashdown Gorge Wilderness, some private land and nearby Flanigan Arch.
