There are two courses marked out with arrows and signage saying "Long course" or "Short course". The short course option misses out most of the more technical and uphill trail sections and is suitable for most riders. The long course includes everything built to date and does include plenty of climbing and technical sections. The recently completed berms and table-top jump section is a hit with riders and even rideable by younger members.
Feel free to bring your bike and go for a hoon if you're into that sort of thing. If not, enjoy the walk around the paddock. The house across from the entrance is aware of the imminent arrival of cars that may or may not have bicycles. The gates are normally closed but you can gain access by hopping over the style.
The caches are hidden amongst trees so I've tried my best to get the most accurate coords, so if you think they're out, let me know.
There is a small prize for the FTF.
