Its not really a trail, but a Super Slalom course with big doubles, berms, and table-tops. If your into dual racing they have races that started in 2000. Check this place out if your in the area for sure.
How to get there:
Easiest way to get there is to take 580 East until you get to Vasco Rd. Go North on Vasco until you get to the first stop light. (It's a ways) The road should be Camino Diablo. Turn left on Camino Diablo and drive until you see it on your left, you can't miss it.
This place is the ultimate bike park. It has a downhill, duel slalom and even a biker X track. all t
