Garnet Hill and Hellroaring Trails, located near Tower-Roosevelt, offers three hiking options with distances between 4 to 10 miles. To access the Garnet Hill Loop Trail, park in the large parking area to the east of the service station at Tower Junction. Walk down the road toward the Northeast Entrance Road (approximately 100 yards/91 m) and head west on the dirt stagecoach road about 1.5 miles to the cookout shelter. Continue north along Elk Creek until nearly reaching the Yellowstone
River. Here the trail divides, with the west fork joining the Hellroaring Trail and the east fork continuing around Garnet Hill and eventually returning to the Northeast Entrance Road where it is a short walk back to Tower Junction.
The Hellroaring Trail can be reached from the fork of Garnet Hill Trail (see above) or you can start from the Hellroaring parking area 3.5 miles (5.6 km) west of Tower Junction. Follow the trail over the Yellowstone River Suspension Bridge, cross a sagebrush plateau, and drop down to Hellroaring Creek. The Yellowstone River and Hellroaring Creek are both
popular fishing areas.
Note: This trail can be hot and dry during the summer months. Please remember to take water! Also, watch your footing if you go off-trail and onto the smooth river boulders along the Yellowstone River.
