"Snaking, cracking, shimmering a brilliant blue in places and covered by mystical frost in others, the Mer de Glace displays nature in all its powerful glory. France’s longest glacier stretches for 4.3miles and is over 650 feet deep. Quite literally a sea of ice, it continues to move under its own weight; its surfaces break up, crevasses appear, and pointed columns of ice known as seracs burst from the surface. Though this glacier continues to amaze,it’s slowly being decimated byclimate change—in 1988, you only had toclimb down three steps to reach the ice grotto, which is carved out every spring; now, the ice has receded so much that you have to tackle 430 steps."

Beautiful ice caves after taking a cog train up the mountain. It's a little bit of a walk to go down to the ice caves, but totally accessible as there are metal stairs and railings. The ice caves are neat, with different areas great for taking pictures such as ice chairs, bars, and such. A fun area to explore for a few hours.

Beautiful place we took the Montenvers train from Chamonix and reached the mer de Glace only to know that they closed early due to olympic light activities. The views at the top were gorgeous!! The 20-minute train ride was one of the beautiful rides !!

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). The 20 minute train ride is relaxing, but once you reach the top, you'll have to take a cable car down & continue to climb down about 400 steps to see the ice cave.

Visited on a Wednesday, early January 2023. Cute little red train, with big windows takes you to the top. From there you take a gondola down to the bottom, from there walk to glacier. Extremely beautiful.

A must see. Bring water and a jacket for inside the cave. Squeeze this into your multi-pass. This 1,913m glacier will have your jaw dropping from this unique sites. Allow for enough time to enjoy this beautiful place.
