Land Owner
GP is a high-speed trail that weaves down the side of the hill with high berms and a variety of blue/black features, some of which have mandatory gaps, but all of which have intermediate-friendly ride-around options. Upper and lower GP are divided at the point that Baby GP enters. Lower GP is a popular section of a ‘hot lap’ whereas the entire trail is usually ridden after finishing Badmotorscooter. Trail surface is 100% high clay content dirt so stay away in freeze/ thaw or wet conditions as it is dangerously slick and more importantly, it ruins the wetter sections of trail. Trail is sign posted as a black, but intermediates and confident beginners should have no problem cruising down using the ridearound options to avoid the more advanced features.
Access Info
Starts from Riordan HIll Road at the top of lower 8 track, the bottom of upper 8 track, and the bottom of Bad Motor Schooter.
Disclaimer
New features as/of April 1 2021.
