TTFs on TrailRock Garden, Skinny
Starts opposite Clifftop, with the first part being short section of TBC (Black). This first section is flowing with some technical (but rollable on the right line) rock/drops. A steep right into a slope that merges into short (and small) left hand berm leads onto Third rock.
This middle section of the trail (the first part of Third Rock) is fairly tame. There is section of low skinnies, about 25 yards long, these are reasonably robust and start at about 1 foot wide and gradually get thinner with each section - the finishing skinny is a single plank in width and quite tricky.
This then leads to the final section, which is relatively steep and includes three (and a small fourth) rock rolls, these rock rolls are all rollable, again if you pick the right line. These lead to an easy and fast down hill end section.
This is largely a natural trail.
