From the Carson Lake parking area, ride across the dam, and head out on the singletrack to the south. The trail starts out gently, whooping along through fun meadows and glades of pine and aspen. Oftentimes many elk are seen in this area.
After a few miles, the trail begins to roughen, and intersect with other trails (Coal Creek, Indian Point). The signs were intact last time I rode it, but have been missing (or missed) at other times. Stay on The south side of Kannah Creek, on the main trail.
The trail will become more and more brutal as you go, until you near the end. Watch for jagged branches and hidden rocks and roots, as the trail can become overgrown. The last 5 miles or so transition to desert riding through pinon, juniper, and cedar, and are very fun and fast, if you haven't injured yourself or broken something.
