Route Details

The Teton Connector links the WWR 20 miles east of Blackfoot, Idaho to the GDMBR at the western end of the Ashton-Flagg Ranch Road. The route leaves the Snake River Plain via a mix of agricultural lands and shallow canyons, passes several hot springs, and climbs over the rugged Big Hole Mountains. Dropping into Teton Valley, the Teton Mountains loom impressively to the east above more farmland and the community of Driggs. At Driggs, the route turns north and mostly gravel roads and the Ashton-Tetonia Rail Trail to the GDMBR. Most of the riding on this route is on well-maintained dirt/gravel roads or quiet pavement, but the roads over the Big Hole Mountains are rough, loose, and steep by comparison.
