My friend with the apartment there has suggsted the following itinerary – feedback and any suggestions welcome from any experts!
Friday 29th – Half day only, so new runs at La Flegere. Red, can be cycled to. Probably do twice.
Saturday 30th – Big day. Bus to La Tour. Cable car to Balme and ride over and down to Vallorcine. Black. Do again then back up and easy Red, Le Tour to Argentiere and up lift to Logan. Down our standard hard Red to Le Lavancher. If tired back to Chamonix, else do La Flegere again.
Sunday 1st – Full day. Les Houches: bike park, Black run (but looks like you have to cycle up). Prepared track from the Bike Park all the way down. Up again and the route under the lift we found last time. Up again and finally the long circuit around the back and down to Les Houches. Back to Chamonix
Monday 2nd – Half day. Bus to Argentiere, lift to Logan again. Down to La Lavancher and across to La Flegere again. Back to Chamonix.
Can get a lift pass for all lifts – except Les Houches- for €20 per day. Not sure about half days
