These trails are primitive. Navigation is difficult. Be prepared with a GPS track or bring a Guide.

Big Idaho Shuttle dropping over 6000' on Thunder Mountain and Henry Creek Trails from the top of Lake Mountain to the Salmon River.

This is Idaho backcountry riding at its finest.

This ride takes 1.5-3 hours without the shuttle setup. There is a climb on Forest Road from Thunder Mountain to Henry Creek (Upper) and Upper Henry itself has some climbing before the bottom drops out.

Start the ride on the Ridge Road near the top of Lake Mountain, not because it is convenient but because you are antsy to get out of the car and onto your bike. At least an hour is needed to get to the Dropoff. Pick up is at Henry Creek Trailhead.

      The trail is in great shape for the most part. The notable exceptions are the three logs across the trail and the portion of the trail that the creek runs down in the spring. Even with these fixes needing to be made this is still one of the best rides right now.

      The Ridge Road is groomed for snowmobiles. Don't expect virgin corduroy, but it is usually firm enough to ride. Ridge Road south from Wms Summit sometimes is rough from the FAA maintenance cat that visits Lake Mtn.
