“A tech climb to a tech descent breaking into fast flow that begins in a massive alpine valley.”
— Blaine Myers
Snow in winter.
Off 191, turn onto Upper Hogback River Rd., and drive to Kilgore Crk Rd. / FS Rd. 30710. Drive to and park at FS gate. From here ride past the gate and over a new log bridge that crosses Kilgore Creek where the trail begins.
The trail ascends through a meadow on gentle grade in the shadow of lesser Wyoming Range peaks (this area has awesome backcountry skiing in winter) and dips in and out of woods to the first and only Kilgore Creek crossing. Ride or hop to the trail on the other side (much swifter in the early season, you'll get a little wet).
From the other side of the creek, the trail ascends singletrack up a bench at a gentle grade for approximately one mile. Here you can see a trail that branches to your right, this would be a nice ride, but is impeded by copious deadfall. Stay straight as the trail ascends back into woods.
For a short section, the trail becomes extremely steep and technical. For most, if not all, this area requires an approximately 1/4-mile hike-a-bike on the ascent and descent. This spot is very steep, rooty, and if it has rained, muddy. However tempting, don't turn around here. The Forest Service out of Big Piney has done an excellent rehabilitation job on a forgotten trail above this technical section.
The second section here is rolling technical singletrack that ascends over 1.5 miles to a lush valley in the Hoback Peak Massif. Here, there is an awesome backcountry campsite where I mark as the turnaround point. The trail continues past this point, but very steeply up the east flank of Hoback Peak to a picturesque waterfall. Definitely a worthwhile hike.
From the backcountry camp, turn around and rip. The descent is technical and tight through thick woods then after the hike a bike, is wide open and fast with rollers and swoopy turns. As, I wrote above, this was an old trail that the USFS recently cleared and rehabbed. Beautiful.
