Spearfish to Alpine: Ultimate Road Trip Guide

Begin your journey in Spearfish, South Dakota, where US-14A twists through the breathtaking Spearfish Canyon, a 1,000-foot-deep gorge carved by ancient waters. This route to Alpine, Wyoming, crosses the Wyoming border near Beulah, offering a scenic corridor that transitions from Black Hills pine forests to high desert sagebrush plains.

Driving time from Spearfish to Alpine typically ranges from 1.5 to 2 hours, covering approximately 70 miles (113 km). The fastest route is I-90 West, but the more rewarding path is US-14/14A, which hugs the canyon and provides access to numerous overlooks and waterfalls.

Drive with caution: the canyon's sharp curves and wildlife crossings (deer, elk) demand attention. For families, the Spearfish Canyon Scenic Byway offers easy access to trails like the 0.5-mile loop to Roughlock Falls, which is stroller-friendly but not wheelchair accessible. Picnic areas are plentiful.

Pets are welcome at outdoor stops, but keep them leashed due to wildlife. There are no dedicated dog parks, but the national forest allows off-leash in remote areas. Rest zones are limited; plan for breaks at Beulah's Buckhorn Bar & Grill (human-friendly) and the Spearfish City Campground before departure.

To combat fatigue, alternate drivers on long stretches. The drive is short, but mountain roads can be mentally draining. Consider stopping at the historic Latchstring Inn, where you can stretch legs and grab coffee. Hidden off-route gem: the abandoned mining town of Tinton, accessible via a rough gravel road, offers a glimpse into the area's gold rush history.

The canyon's geological wonders include towering limestone pillars and the 80-foot Bridal Veil Falls, a must-see photo stop. Beyond the falls, the route passes through the Black Hills National Forest, part of the larger U.S. Forest Service network. Alpine, Wyoming, sits at the base of the Snake River Range, offering a gateway to Bridger-Teton National Forest and the Salt River Range.

Local commerce along the route is modest; you'll find small cafes in Beulah and a handful of shops in Alpine. The historic Spearfish Canyon Lodge offers dining, but for unique local flavor, try the baked goods at the Beulah Country Store. Additionally, the route touches the edge of the UNESCO-designated Greater Yellowstone Ecosystem, though the main attractions are further west.

The climate here is semi-arid: Spearfish sees 18 inches of rain annually, while Alpine receives slightly more due to orographic lift. Summers are pleasant, with highs in the 80s (°F), while winters bring heavy snow to the mountains and occasional closures of Spearfish Canyon. The best time for aesthetics is autumn, when the canyon explodes in gold and crimson.

Fuel up in Spearfish before heading out—gas stations become sparse once you cross into Wyoming, especially near Alpine. The last reliable fuel stop is in Beulah, Wyoming (about 20 miles from Spearfish). As of 2024, gas prices average $3.40 per gallon in South Dakota and $3.25 in Wyoming.

Road quality on US-14A is excellent, with well-maintained asphalt and clear markings. Winter conditions can be hazardous; check road reports before traveling. Spearfish Canyon is prone to rockfalls and icy patches even in early spring.

• No tolls on this route.
• Cell service is spotty in the canyon but improves near Beulah.
