CDT - Jahnke Loop is a remote backcountry ride that follows an amazing section of the Continental Divide Trail through the Beaverhead Mountains.

2012 saw the CDT route changed to newly constructed trail along the divide and then down to Jahnke Lake. Huge views of Idaho's Lemhi and Salmon River Valleys to the West and Montana's Big Hole Valley to the East are to be had.

This Loop follows the Goldstone Jeep Road as the "easiest" way up to the top of the divide and the CDT from the Skinner Meadows Road, climbing roughly 1600'. The CDT then follows closely the crest of the Beaverhead Mountains above the Darkhorse and Wimpey drainages before dropping into the North end of Darkhorse.

There is a steep climb back out of Darkhorse to a saddle and a view of the Jahnke drainage. The descent here is steep and can be technical, but highlights some amazing trail building, as it winds down toward Jahnke Creek.

Nearing Jahnke Creek is a trail intersection. The main route heads right and down. Taking a left here gives a worthy and short side trip up to Jahnke Lake and the old mining cabins there.

The descent from the Lake down to Skinner Meadows is straightforward singletrack. The Overland Trail begins just after the Jahnke "trailhead" and the road there. Look for an old small sign marking it.

Camping: There are many informal camping areas in Skinner Meadows. Reservoir Lake Campground is a few miles south of Goldstone Jeep Road. Bloody Dick Cabin is a USFS Rental Cabin near Reservoir Lake.
