For the duration of the course the area that we will use will be covered by Chamonix Le Pass. However if you intend to ski off the top lift at Les Grands Montets, the Aiguille du Midi, ski in Courmayeur or Les Houches during times outside of the course then I would recommend getting the Mont Blanc Unlimited Pass.
In the event of bad weather we may choose to use Les Houches and this is not covered by Chamonix Le Pass. However, you can upgrade the Chamonix Le Pass for the duration left on the pass to a Mont Blanc Unlimited, or buy a day pass for Les Houches.
If you are in Chamonix regularly it would be worth considering getting a Chamonix Rapid Card. You pay 50 Euro for the card and are then charged for what you use so that you don't need to queue for a pass each day.
If you are unsure about which pass to buy then I recommend that you wait until we meet on the first day of the course to purchase your pass.
