Black Canyon of the Yellowstone Trail

Length: 19.0 miles (with the detour to Knowles Falls)
Trail Begins: Hellroaring Trailhead
Trail Ends: Blacktail Creek Trailhead

The Yellowstone River Trail travels from Hellroaring Trailhead to Blacktail Creek Trailhead. The trail follows the Yellowstone River, passing a variety of interesting features along its 16 mile length. For most of the way the river flows through the Black Canyon of the Yellowstone. This canyon is over 1,000 feet deep and in many places the dark canyon walls rise vertically from the water's edge. The western end of the canyon contains Knowles Falls, a 15 foot drop of the Yellowstone River. With the closure of the Gardiner Trailhead this trip would require some backtracking and approximately an additional 3 miles. You'll find that when a river this size drops even a mere 15 feet, the result is impressive.
