Description

Originally built by Brent Rayner and Chris Brown, and revamped in November 2020 by Trail Pro. A clay based trail that winds its way from the upper park to the lower. Fast and dusty in summer but muddy and wild in winter. Has many berms and doubles. Watch the exit as trails merge as you return to the road. North-facing, so dries a bit faster than most other tracks in the forest.
