This byway will lead you on a delightful adventure as it winds its way around spiraling pig-tail shaped bridges, through six rock tunnels, among towering granite pinnacles and over pristine, pine-clad mountains. Highlights include Mt. Rushmore, Harney Peak, Sylvan Lake, the Needle s Eye and Cathedral Spires rock formations.

We publish 6 places that sit on this road, listed in the order you meet them. This is not a route and not a drive time — it is the names, so you can put them into whatever navigation you already use.

“Off” is a straight line from the place to the road, rounded. It is not a driving distance, and the road itself is a simplified centre line, so treat a mile or two as noise.
