Start at the parking next to the street and follow the creek (you might have to cross it two or three times). It navigates you in a valley called Val Fonda. Follow through that valley until you are almost at the end, until you see a narrow and steep canyon that is located on your left side. Follow that canyon (you might need your skis on your backpack and use crampons, depending on the snow conditions). After you navigate through the canyon you are on an open field where you can locate the couloir and just keep going in that direction.(you can go pretty much everywhere due to its low avalanche danger. Once you reach the entrance of the couloir, and it is too steep to continue on skis, put your skis on your backpack and follow the line to the top with crampons(Tip: you must only climb this couloir when the snow pack is consolidated and hard as you don't want to break trail on a deep trench and get exhausted before you’ve even begun to ski down) You might encounter rocks on the way up, so keep them in mind when you are skiing down again.
