This is a very fast hairy track it is hella fun though, has a lot of rocks and rain routs, and it has patches of sand. Their are hell of birms though and it is so worth the hike to get there. Irecomend atleast 4 inches of front travel, rear travel is good but a heavy bike is a pain to ride or dare i say hike up to the top of the trail.
Go up yagnacio vally road to the set of lights at the top. Go on to the land to yor right. There will bee a very large damn/retainer wall at the very back. To to it, hike up to the top, their will be a trail that gos relativly straight go up that it will take you up to the top, their will be a trail to your right and that is it!
