Switchbacks lead up the hill 0.5 miles (0.8 km) to a commanding view of the Upper Geyser Basin. Return the same way.
Safety notes: Carry water and pace yourself going up the hill.
Trailheads: From the Old Faithful Visitor Education Center, walk about 0.3 miles (0.5 km) counter-clockwise along the Old Faithful boardwalk, turn right at the Geyser Hill sign, and continue down the path. The trailhead is just after the bridge crossing the Firehole River.
