Is it signposted? No , NOt really . As you come out of the Super Morzine Cabin/ Bubble take the next chair down and right .
Top of that chair turn right down the hill ona grey gravel road. This road forks , take the left fork and continue straight for around 1 mile. As you approach some trees bear right and down a fast double track that pops you out on a road opposite a restaurant.
There is a junction on this road , straight on is Avoriaz. You need to take the left turn for around 10m or so. There is a gully that might be marked PDS route . Bomb down this its wide and fun and fast in places . This will take you round to to top RHS of Linderets. The first chair lift will drop you toward Mogrim / Champery WC DH track ( not for the girls ) , or follow the double track down hill to the 'center ' then its 1 lift up and over to Chatel.
