The Montenvers train departs from Chamonix and makes its way up the sides of the Aiguilles de Chamonix to an altitude of 1,913m. The train takes you to the Mer de Glace, the Ice Cave and to two wonderful restaurants.
The train will close from the morning of 30 September until the evening of 18 October included.
The Compagnie du Mont-Blanc, together with the help of external companies, will change 650 linear metres of century-old track "rack and steel sleepers" below the Planards crossing towards Chamonix.
Furthermore, to ensure that the operation will be safe, some trees located right at the side of the track will be cut down.
As a result, mountain biking and walking on the 4x4 Planards track and the Mottets trail between the crossing of the Montenvers trail from Caillet and the Fillaz trail are prohibited, as per mayor's orders.
"During this autumn closure, we will also carry out our annual maintenance work on the Mer de Glace gondola and continue our studies related to the evolution of future projects", end the CMB their press release.
