The Mer de Glace (Sea of Ice) is the largest glacier in France, 7km long and 200m deep and is one of the biggest attractions in the Chamonix Valley.

To access the Mer de Glace and the Ice Cave in Chamonix, take the train of the Montenvers from Chamonix town center (Gare du Montenvers).

Mer de Glace Visitor Attractions

1. The Ice Grotto/Cave

A small cable car allows visitors to descend from the train station onto the Mer de Glace glacier where they can enter a man made ice grotto. The ice grotto is cut into the living glacier.

The grotto has to be dug out every summer since the glacier moves about 70m every year.

Access is via 430 steps on both the outward and return walk from the top of the glacier gondola lift.

Ice sculptures and caves are inside, under the glacier. The Gallery of Crystals features a collection of the finest crystal specimens in the Mont Blanc massif.

2. The Glaciorium

Established in 2012 on the site of Montenvers Mer de Glace and open daily during the summer (early June to late September), the Glaciorium features an entire exhibition dedicated to glaciology, with interactive and educational presentations all about glaciers, how they form, their history. It also answers questions related to climate and the environment.

A glacier is a climate indicator. It is also the memory of the planet and life on Earth.

The museum also explores the culture built around the glaciers, how they will change in the future and more.
