Bridger-Teton Backcountry Loop (Greys River Road)
Salt River Range high country loop
The Greys River Road serves as your gateway into the heart of the Salt River Range, where Wyoming’s backcountry still runs wild and uncompromised. Starting near Alpine, this loop follows the Greys River drainage south before climbing over McDougal Pass at 9,400 feet, then descending the Smith’s Fork drainage back to civilization. Multiple creek crossings keep things interesting, especially during spring runoff when the water runs high and cold.
Rated moderate to difficult depending on conditions—spring crossings can be tricky, and the pass gets snow well into July. Stock 4WD with skid plates recommended, plus tow straps and recovery gear. Prime season runs August through September for best conditions. No permits required, but fuel up in Alpine and carry extra water. The reward is pristine fishing, abundant wildlife, and camping spots that showcase why Wyoming earned its reputation as the last best place.
