From the parking head north and cross a bridge to get to a single poma ski lift. Climb the piste at the side of the lift until the lift finishes, from there continue north up a gully (normally steep skin tracks). At the top of the gully cross a small flat road and continue north picking the best line until the trees, then from there it is a short climb to the cross. Often the section to the cross can have poor snow, (the GPX trace finishes at the end of the trees, but you can see the cross).
Ski down roughly the same way you came up.
