Keystone to Lander: Scenic Byway Road Trip Guide

This route from Keystone, South Dakota to Lander, Wyoming crosses the Missouri Plateau into the Rocky Mountains, following US-16 west through the Black Hills, then I-90 and US-14 across Wyoming's high desert to US-287. It's a drive that spans 450 miles and climbs over 5,000 feet in elevation, with the entire trip taking about 6 hours and 15 minutes of pure driving time.

The route showcases a transition from granite peaks of the Black Hills to the red gorges of the Badlands and the high plains of Wyoming. Look for bighorn sheep near Devil's Tower (a UNESCO World Heritage Site) and along US-16 in the Bighorn Mountains. The region's mining history is visible in old ghost towns like Cambria; local shops in Lander sell authentic Shoshone crafts and Pendleton blankets.

Culinary stops range from classic American diners to Wild West-themed saloons. Newcastle's 'Shotgun Sally's' is known for its bison burgers, while Thermopolis offers the Star Plunge, a naturally heated pool complex. For a real taste of the Old West, try the Cowfish in Lander, a biker bar that also serves top-notch steaks.

The roads are well-paved and free of major hazards, but weather can be unpredictable. In winter, carry chains and check forecasts for the Bighorn and Wind River passes. Summer brings afternoon thunderstorms; autumn is clear and cool, with golden cottonwoods lining streams. For family breaks, visit the Mammoth Site in Hot Springs, SD, where kids can see fossilized mammoth bones, or the National Museum of Wildlife Art in Jackson (though it's a slight detour). For pets, most rest stops allow dogs on leashes; the KOA in Buffalo has a dedicated dog park.

To manage fatigue, plan stops every two hours. Notable rest areas include the scenic overlook at Sundance Mountain (mile 50 on I-90) and the Wind River Canyon rest stop (mile 112 on US-20). Hidden gems off the route include the skeletal fossil trails near Lance Creek, WY, and the petroglyphs at Legend Rock (north of Thermopolis). For a detailed approach to discovering such gems, see how to find the best stops and hidden gems between cities. The route is ideal for families: the stops are educational, and the drive is smooth. However, keep a crash kit for pets, as veterinary services are sparse in rural areas.
