Driggs to Thermopolis: A Wild West Road Trip Guide

Leaving Driggs, Idaho (elevation 6,200 ft), you cross the Teton Pass via ID-33 eastbound, a route notorious for its 10% grade and hairpin turns. The pass, which tops out at 8,431 ft, offers a dramatic descent into Jackson Hole, Wyoming. This road trip spans roughly 200 miles (320 km) and takes about 4 hours of pure driving time, not counting stops. The asphalt transitions from Idaho's rural two-lane highways to Wyoming's open plains on US-26/US-287, ending in Thermopolis, home to the world's largest mineral hot spring.

The journey crosses two major geological provinces: the Snake River Plain and the Wyoming Basin. Along the way, you'll encounter the Gros Ventre Range, the Wind River Canyon, and the Owl Creek Mountains. This route is a condensed tour of the Rocky Mountain West, offering everything from alpine meadows to badlands. Planning stops is essential, as gas stations and services are sparse after Dubois, WY.

Jackson itself is a tourist hub with art galleries and cowboy culture. Continue east on US-26 through the Bridger-Teton National Forest, where the Gros Ventre Range rises to the south. Near Dubois, the terrain opens into the Wind River Basin, a high desert dotted with sage and juniper.

The Wind River Canyon, a 10-mile stretch along US-20, is a highlight with sheer rock walls and the Wind River running alongside. This is part of the ancestral lands of the Shoshone and Arapaho tribes. Thermopolis lies at the southern edge of the Bighorn Basin, known for its hot springs and dinosaur fossils.
