Starts off with some off-camber switchbacks and rapidly mellows out to become fast and wide open where it crosses the fire road. There's a small gap jump with a b-line to the right, and then a few more turns until you come out at the bottom of Community College.

This trail is unsanctioned.

      Neglected by maintenance and riders alike, probably for good reason. Large tree down after the gap, very easy to see and stop. Easy portage.

      Climb a bit more and do a different trail.

      It's more like a slightly steeper than usual single black but they're really isn't A whole lot to it other than some steepness at the top with some steepish turns and then a fun little trench/small gully option with some short wavey turns. The rest is moderately steep single track through trees and coming out at the bottom of community College. Overall probably the easiest "double black" trail here and its over pretty quick...overall it's an OK if you don't have enough time to get over to the Deadass area but that area is way more fulfilling than this.

      We hope you've been enjoying Trailforks!
