Almost half a mile of single track with several off-camber sections - but all 100% doable without footholds (but they sure would help). At the first intersection with 3 single tracks stay on the middle one going left. Then at the next intersection turn sharp right. If you see a park bench or chairs you've gone too far - turn around! After the final single track section you'll hit the fire road. Stay on the fire road all the way - try not to die on the final downhill.
Start Point
At a 5-way intersection before Patriot Trail goes up the steep hill there's a single track heading left
End Point
Intersection of Patriot Trail and Forster Canyon Trail - before the first steep uphill
Directions from Parking to Trail
Take the main fire road from the parking lot till the first opportunity to turn left onto a fire road - take that uphill to the big intersection.
