This condensed trail is hidden in between apartment complexes and neighborhoods. You will find packed dirt lines with rooty obstacles and the occasional limestone rocky feature. There is a hidden jump line skills park you can hit for fun as well as parallel drop lines. Ranger drop is also a Hermes trail, but not part of the Underground.
Start Point
Follow the trail sign to the Red loop and begin at the forked trail where it splits between red and blue loop. The segment begins near the wooden bridge.
End Point
The red loop segment ends right before you get back to the beginning feature (Whole Loop)
Directions from Parking to Trail
