This is the only one-way trail in the Fire Mountain Trail System. Downhill only—do not try to climb this trail.
Kessel Run starts at the very top of Fire Mountain and can be accessed by climbing either Spearfinger or Uktena. The trail crosses over Waya at a horseshoe-shaped wooden bridge and crosses Lazy Elk at the 1.8 mile mark before ending at another intersection with Lazy Elk. If you add the end of Lazy Elk and Kate's Wave to this run, you get a 3.5 mile total downhill. The terrain is mostly smooth singletrack with tons of berms, rollers, a few jumps, and one optional technical rock garden. The flow is almost endless!
