Fast loop with two entrances, with smaller berms - relatively smooth and fast rolling.

      Chill loop with very mild ups and downs. Great for beginners, or just turning XC laps. Rocky/bumpy in some sections.

      Straightforward loop; very good for beginners to practice fundamentals.

      The brush is getting thick but the trail still runs well.

      We hope you've been enjoying Trailforks!
