Just on the other side of Predator, steep technical turns and rock features.

Most folks hike-a-bike up Predator in order to descend Alien VS. Hiking up Alien VS to descend Predator would not be worth it.

      This trail is a lot less rocky than most other black diamonds out here so I recommend riding it before other trails like overwatch, etc. Its really fun though and a great downhill.

      This is a super steep descent when heading NW. Not climbable uphill via pedaling.

      We hope you've been enjoying Trailforks!
