“This steep singletrack gets the legs scorching or the adrenaline pumping.”

Going in the uphill direction (starting in the north and heading south), East Fork starts as a wide and fairly smooth and straight singletrack. On the last 1/3 of the trail, your legs will get hammered with an extended steep climb in stair step fashion. At the top of this hill, you'll be looking down on Highway 73.
At the top of the East Fork hill, the trail degrades significantly on one side. Along with the rocky terrain on that section, one bad move and you may regret it. Downhill riders could net serious speed on East Fork. Watch for hikers. I didn't see any other bikers on this trail, and I'm pretty sure I understand why now.
East Fork is only accessible on IRC Wilderness Access Days for Bommer Canyon.
