The Continental Divide Trail is a footpath running 3,100 miles (5,000 km) through the United States of America between Mexico and Canada. It follows the Continental Divide along the Rocky Mountains and traverses five U.S. states – Montana, Idaho, Wyoming, Colorado, and New Mexico. In Montana it crosses Triple Divide Peak which separates the Hudson Bay, Atlantic Ocean and Pacific Ocean drainages.
As of 2004, the trail, a combination of dedicated trails and small roads, is considered 70% complete. The uncompleted portions of the trail must be traveled by bushwhacking or roadwalking.
Only about two dozen people a year attempt to hike the entire trail, taking about six months to complete it.
