Fast flowy machine built ripper opened summer 2021. Steeper than a typical machine built "flow" trail. This is part of the future trail connect to the town of Preston and exit 22. For now it ends at a logging road. Make a right and take the logging road to the East Side Road, Preston Railroad Trail and Silent Swamp Trail.

      Much steeper than I anticipated. It’s not necessarily a technically difficult trail, I mean it has its bumps and roots, nothing mandatory. It’s more so that it’s easy to go uncomfortably fast on this and it has a fair share of tight switchbacks. Don’t get me wrong, it’s fun, but more for people who like speed over the classic tiger tech. It’s faster than side hustle by far. Your brake pads might get melted

      Literally melt your brake pad steep if you ride fast. Was in great condition due to the unseasonable rain we’ve been having.

      Great trail - lots of fun. Definitely blue, but also not easy blue.

      We hope you've been enjoying Trailforks!
