Stanley to Midway: Scenic Drive Guide

The drive from Stanley, Idaho, to Midway, Utah, spans roughly 340 miles through the heart of the American West, crossing the Snake River Plain and the Wasatch Range. The route begins along ID-21, a narrow mountain road that climbs from the Sawtooth Valley to the historic mining town of Atlanta, before descending into the high desert.

The core highway is US-20 east through the Sawtooth National Recreation Area, then US-93 south past Craters of the Moon National Monument, and finally I-84 and US-189 into Midway. The road surface is consistently smooth, but note the 55 mph speed limit in many sections.

• Fuel stops limited: fill up in Stanley or Hailey before crossing the desert.
• Gas prices drop about 15% south of Twin Falls.
• No tolls on this route.

The route is generally well-maintained, but wildlife crossings are common at dusk. Family-friendly stops include the Idaho Potato Museum in Blackfoot (estimated entry $8) and the Bear World wildlife park in Rexburg, both just off the highway.

Fatigue is mitigated by numerous rest areas every 50 miles, and the town of Burley has a 24-hour truck stop with showers. For pet owners, most rest areas have designated off-leash areas, and the visitor center at Craters of the Moon allows leashed pets on the trail.

Hidden off-route spot: the City of Rocks National Reserve, a 10-mile detour near Almo, Idaho, known for its rock climbing and pioneer inscriptions.

The route skirts the 750,000-acre Sawtooth Wilderness, where granite peaks reflect in alpine lakes. The landscape transitions to black basalt fields at Craters of the Moon, a UNESCO World Heritage Site candidate, with lava tubes and cinder cones. Here, the local Shoshone-Bannock tribes have interpreted the volcanic terrain for centuries.

In the small towns of Bellevue and Shoshone, local diners serve huckleberry pancakes and hand-cut steaks, reflecting a ranching heritage. The midpoint at Twin Falls offers the Snake River Canyon, where the Perrine Bridge attracts BASE jumpers.
