This 51.6-mile challenging backcountry route weaves through some of Idaho’s most stunning wilderness, combining river valleys, alpine basins, and rugged mountain terrain. It is recommended as a 4-5 day backpacking trip and ideal for anyone looking to spend extended time in the backcountry, gain access to a variety of mountain peaks, and hike alongside rivers and scenic lakes.
Start along the Middle Fork Boise River Trail, following the river upstream through lush forest and occasional open meadows. After gaining some elevation, connect with the Tenlake Basin Trail, which guides you toward the high alpine basin region.
Take the Tenlake Basin Trail to the Ardeth Lake Trail and enjoy this beautiful area passing by Vernon, Edna, and Virginia Lakes. Next, continue to the Mount Cramer Trail, which climbs steeply toward Cramer Lake. The trail offers breathtaking vistas of surrounding peaks, alpine ridges, and clear mountain lakes. Cramer Lake is a rewarding destination for an overnight camp or a long break before the return.
On the return, head south toward Virginia Lake, but before reaching it, turn west at the junction onto the South Fork Payette River Trail. Follow this trail until the next junction and turn south reconnecting to the Tenlake Basin Trail. From there, retrace your steps to return to the starting point.
Flora and Fauna
The route passes through diverse ecosystems, including old-growth forests, wildflower-filled alpine meadows, and rocky high-country terrain. Expect to see Douglas fir, lodgepole pine, and subalpine fir trees. Wildlife sightings might include mule deer, chipmunks, porcupines, black bear, mountain lion, pine marten, wolverines, various bird species and more.
PERMITS AND CAMPING
Permits are free and can be picked up from the trailhead. Check with the local ranger district for current trail conditions, updates regarding permit requirements, and any fire restrictions. Backcountry camping is allowed, but practice Leave No Trace principles to protect this pristine wilderness.
