The CDT between the east flank of Goat Mountain and Lemhi Pass is two-track. The road pretty much follows exactly the crest of the divide. There are wide open alpine meadows separated by timbered sections. The CDT can be flat and easy or very steep up/down; expect some hike-a-bike on the steeps. The road loses a lot of elevation as it nears Lemhi Pass.
Access to water sources are signed along the trail.
