The Continental Divide Trail (CDT) is a long-distance hiking trail that follows the Continental Divide of the Americas. Spanning approximately 3,100 miles, it runs from the U.S.-Mexico border in New Mexico to the U.S.-Canada border in Montana. The trail traverses diverse landscapes, including mountains, forests, and deserts, offering hikers a unique experience of the natural beauty of the western United States. Established in 1978, the CDT is one of the three major long-distance trails in the U.S., alongside the Appalachian Trail and the Pacific Crest Trail. It is managed by the U.S. Forest Service and various state and local agencies, ensuring its preservation and accessibility for outdoor enthusiasts.
