| Road | Length | |
|---|---|---|
Badlands Loop State Scenic Byway (SD-240) SD-240 twists for 39 miles through Badlands National Park between Cactus Flat and Wall, curving through a wall of eroded pinnacles and buttes with 16 scenic overlooks. There is no fuel inside the park, and summer heat on the exposed prairie can be intense. | 35 mi | |
Iron Mountain Road (US-16A) US-16A between Custer State Park and Mount Rushmore packs 314 curves, 14 switchbacks, three wooden pigtail bridges, and three single-lane tunnels engineered to frame Mount Rushmore in the windshield. Ride it south-to-north for the tunnel framing, and expect heavy tourist traffic in summer. | 31 mi | |
Spearfish Canyon Scenic Byway (US-14A) US-14A winds through a 1,000-foot limestone canyon between Spearfish and Cheyenne Crossing, passing three waterfalls along Spearfish Creek; the area appeared in Dances with Wolves. The mapped route follows all of US-14A, which continues past the canyon through Lead and Deadwood back to I-90. | 44 mi | |

Why ride South Dakota?
Switchback scores every road in South Dakota by corner density and elevation, not by how fast it gets you somewhere. The result is a shortlist worth the detour — Badlands Loop State Scenic Byway (SD-240), Iron Mountain Road (US-16A), Spearfish Canyon Scenic Byway (US-14A) among them — each mapped mile by mile with the fuel stops, overlooks, and bailouts that actually matter on two wheels.
Plan before you ride
Mountain and high-desert routes in South Dakota can be seasonal — verify pass and weather conditions before you commit, top off fuel before long service gaps, and check the mile-by-mile breakdown on each road's page for the named corners, stops, and turnarounds.
