Yep that last section to the valley is AMAZING.
However, at the moment they are building a new piste where it starts, so it's not obvious how to get there. IT IS WORTH FINDING!!!
From the bottom of the 4-man chairlift that takes you up the final section, ride down the set of stairs behind the restaurant there, turn immediately right in the car park, ride down the rough fire road and up the other side, you should then see the start in the tree line. It's one of my favourite sections of trail in the world, has a bit of everything. VERY steep in places, fast singletrack in places, some 4-5ft drop offs, a little ridgeline riding, and a crazy fast section through trees to end.
Enjoy!! Very jealous 🙂
