The Yellowstone River Trail begins on the west side of Hellroaring Creek, 2.3 miles from the Hellroaring Creek Trailhead and ends at Eagle Creek NFS Campground on the Jardine Road, 3 miles north of Gardiner, MT.
From the trailhead, the trail climbs away from both Hellroaring Creek and the Yellowstone River and tops a 500 foot ridge at 1.8 miles. Going down the other side you cross Little Cottonwood Creek and get your first glimpses of the Yellowstone. The trail continues dropping - by 3.3 miles views of the river are excellent and by 4 miles you’re at river level. The wild Yellowstone River begins south of the park and travels 670 miles before joining the Missouri River near the MT-ND border. It's the longest un-dammed river in the lower 48.
The trail continues alongside the Yellowstone, passes a junction with Blacktail Deer Creek Trail
at 7.1 miles, passes Crevice Lake at 7.3, crosses Crevice Creek at 8.3, and reaches impressive Knowles Falls at 9 miles. Though only 15 feet high, the falls makes quite a roar and the scenery is excellent. In the 1870s & 80s John Knowles lived and prospected illegally in the park. When his cabin near the mouth of Crevice Creek was finally discovered, the government ran him out.
From the falls, the trail continues closely along the river. At 10.2 miles, the water turns white and the most dramatic portion of the run is reached as the trail winds through a massive rock slide with excellent views at every turn. Members of the Washburn Expedition of 1870 described the Black Canyon as "grand, gloomy, and terrible . . . an empire of shadows and of turmoil."
At 13.6 miles the trail crosses Bear Creek on a footbridge. Thereafter, you'll notice the remains of hot spring activity in the area. Limestone deposits like these have been commercially mined north of Gardiner. At 13.8 miles a junction is reached. The former Yellowstone River Trail continued straight following the river all the way into Gardiner, MT. However, private land owners in Gardiner, just north of the park are blocking runner access to the trail. As a temporary (hopefully) fix it is possible to turn right and follow a Gallatin National Forest trail up 750 feet over the next 2 miles to Eagle Creek Campground. The good news is the trail is in great shape and it affords nice views back into the Black Canyon and of hard-charging Bear Creek. There’s even some interesting abandoned mining equipment to investigate along the creek.

The area around Hellroaring Creek is frequented by grizzly bears, especially early in the season when they feed on elk carrion that failed to survive the harsh winter. There are also chances to see elk, buffalo, and coyote. Further down, in the Black Canyon, in late spring and early fall, you may spot bighorn sheep among the rocks.
