Iron Mountain Road is actually US Highway 16A.
It is the long, scenic route to Custer. The
road itself starts about a mile west of The Roosevelt Inn and winds for
about five miles to the top of
Iron Mountain -- hence the name. In the first five miles drivers pass
through three tunnels and over two
pigtail bridges. Each of the three tunnels frames a view of Mt.
At the top of Iron Mountain you can pause at a
scenic overlook from one of the highest points in the southern Black
Hills. There is a large parking lot there (closed in winter, however),
and a short trail to the west that offers a terrific view of Mt.
Rushmore and the central Black Hills. It is also a nice area
for a picnic.
next 12 miles the road slowly descents after a series of hairpin
turns and one more tunnel into Custer State Park. Iron
Mountain Road is one leg on the Norbeck Scenic Byway. The north end of
this road is not recommended for large RVs or Motorhomes.
