The Continental Divide Trail (CDT) is a long-distance hiking trail that spans approximately 3,100 miles along the Rocky Mountains in the United States. It runs from Mexico to Canada, following the continental divide, which is the natural boundary that separates waters flowing to the Pacific Ocean from those flowing to the Atlantic Ocean. Established in 1978, the CDT passes through five states: New Mexico, Colorado, Wyoming, Idaho, and Montana. Hikers experience diverse landscapes, including deserts, alpine meadows, and rugged mountain terrain, making it a challenging yet rewarding adventure for outdoor enthusiasts.
