The itinerary from Gentianes to Tortin.
Is this the longest mogul run in the world? From the Col des Gentianes follow the prepared trail North.
At the end of the piste there are a few possible options.
The main run trends right and down the large steep (almost certainly moguled) slope but you can continue straight or slightly left too as shown.
Continue following the main valley line until you reach Tortin.
