This means that you do not fall victim to the communication problems which can be caused by the whole string of contacts and intermediaries on which the tourism industry relies to design and market a holiday (e.g. a call centre based nobody-knows-where and which does not know any more about the holiday than you (or very little), a travel agency secretary who has never done the hike, etc.).
This “paring-down” of the process also gives you access to an unbeatable price without affecting the quality of the holiday in any way.
Moreover, how reassuring it is to have the guide’s phone number when you arrive late at the departure point!
For other types of question (availability, reservations, payment methods or even general terrain questions, etc.) contact the secretary’s office on 00 33 (0)4 50 21 07 75.
