Description by the NPS: "Round trip
3.7 miles (5.9 km), moderate. Begin at the Yellowstone
River Picnic area, 1.25 miles (2 km) northeast of tower Junction on the Northeast Entrance Road. the trail climbs steeply
to the east rim of the Narrows of the Yellowstone River and
then follows the rim. Return the same way or make a loop
by continuing to the next trail junction, where you need to
turn left and descend to the road. (the Specimen Ridge trail,
strenuous and poorly marked, continues northeast.) Walk
west along the road for 0.7 mile
(1.1 km) to the picnic area."
