The first tourist trip on the Montenvers Railway was inaugurated Aug. 9, 1908 and, since then, it has been running non-stop for thousands of tourists every year.
The train is one of the biggest attractions in the valley. The 20-minute train journey covers five kilometres and is famous for its panoramic mountain views.
It departs from the town centre of Chamonix at 1,035 metres and takes visitors to the Montenvers station at 1,913 metres, which is situated on the edge of a glacier.
The Mer de Glace is the longest glacier in France, measuring 14 km, and located on the northern slopes of the Mont Blanc Massif.
A number of the original carriages were beautifully restored this summer and were rolled out to mark the occasion. Summer visitors were invited to commemorate the anniversary by taking the historic journey between Chamonix and Montenvers, followed by tours of the glacier and party evenings on the mountain.
The high point of the festivities was the centenary celebrations on 9-11th August, which was marked by classical performances from Opera en Fete.
