There are 4 or 5 that follow each other. They allow you to work on the noseturns going down and the cardio goes crazy going uphill.

Singletrack on Balcony

Highlight (Segment) • Other

Balcony of pines and heather. Super nice track, not technical but narrow, on an ultra steep sloping balcony. It almost feels like the south. Very cool to do.
