Dunoir Valley Road
Pristine valley road with natural hot springs
Dunoir Valley Road cuts 25 miles through one of Wyoming’s most pristine watersheds, starting from US-287 near Dubois and ending at the Wiggins Fork trailhead deep in the Shoshone National Forest. The road follows the Dunoir River through wide meadows frequented by elk and moose, with the natural hot springs at mile 18 providing a perfect soak after a dusty day of driving.
This easy to moderate route is suitable for stock high-clearance vehicles most of the year, though spring conditions can create muddy sections requiring 4WD. A few small creek crossings and rocky sections keep things interesting without being technical. Open May through October, with peak wildflower displays in July. No permits needed for the drive, but wilderness permits required for hiking beyond the road’s end. Excellent dispersed camping throughout, with the valley’s remoteness meaning zero cell service but world-class stargazing.
