The geographical, cultural, historical and economical dimensions of the Mont-Blanc range has transformed this rural market town into an extraordinary tourist research laboratory. Transversal thoughts carried out for some years to search for a coherent strategy for this exceptional location, have defined global development policies in Chamonix. Chamonix Mont-Blanc presented, at the first Summit, a critical assessment of its tourism development (available in French, here). The actions undertaken today are all influenced by the ideas of a durable development and the public will be able to appraise these steps towards this distinction, during their presentation at the workshops.
