An ideal early-season hike because the snow melts here sooner than in other areas, the Hellroaring Trail drops you down to a sage-filled plateau where bison often gather. Traipse across the open field to reach an impressive suspension bridge that spans a steep, roiling section of the Yellowstone River (the bridge also makes a good turnaround point if you’re looking for a shorter hike). Continue to the banks of Hellroaring Creek and trace it to its confluence with the Yellowstone (both waterways are great for fishing). The trail goes on much farther into the backcountry, but turn around here for a manageable day hike.
