The Col de Balme is the pass between France and Switzerland at the head of the Chamonix valley. It will wow you with one of the finest alpine vistas on the planet. You'll be able to feast your eyes on Mont Blanc and much more before ordering your coffee and gateau at the alpine cafe-restaurant that perches on the pass.
To get there from the top of the Charamillon ski lift you follow the signs to the Col des Posettes (1997m). At that col turn right on the 4x4 track that heads up to the Col de Balme.
From the col (pass) you can ride down into Switzerland (following the Tour du Mont Blanc trail) or take the singletrack that runs under the ski lift back down to the village of Le Tour.
