The Ketchum Ranger District has completed the reconstruction of the trail, which was severely damaged during the 2013 Beaver Creek Fire and subsequent storms. The trail is open.

Description

Begin this amazing alpine trail by shuttling a vehicle or catching a ride to the end of Baker Creek Road FS162. Climb up from the trailhead for a couple miles as the trail heads up Lost Shirt Gulch to the ridge. The higher you get the better the views get.

Once on the ridge the trail climbs and descends many times. There are a lot of uphills heading west to east, but overall you are losing elevation. The trail is well designed and a pleasure to run. Continue east on the main ridgeline trail - stay on the main trail, as some intersections are reached and signs have not yet been replaced following the fire.

The Osberg Ridgeline Trail intersects with the Adams Rib Trail near the east end of Osberg and near to Fox Peak. You can continue east on the Adams Rib Trail #142 back into Ketchum/Sun Valley, or take one of the two connector trails north to the East Fork of Baker Creek Road.
