There are endless possibilities of ski touring between Argentière and Le Tour, including the famous 2 and 3 cols. The option below is a 20 kilometers loop around Col du Passon and Col du Chardonnet. Instead of going down after Col du Passon, I took righ up toward Fenetre du Tour and Col du Chardonnet to get back to Argentière.

Start from Col des Grands Montets (or Bochard and then Col des Rachasses). Ski down to glacier d’Argentière (2,400m) and ski up to the Col du Passon (3,028m).
