Downhill rolling old school track, moderately fast flowing singletrack with some small berms and jumps. Dense forest canopy keeps a lot of the rain off, so this is a good trail to ride when trails are wet elsewhere.

There is the old line at the top that starts at the Double Down entrance and contours along to join where the main entrance now is, not used very much, but is a not little addition to the start of the tail

Access Info

Starts from Katore Rd, a short distance up from the intersection with Nursery Rd.
