This beautiful walk takes you up to the Mer de Glace and the Montenvers station. For those that prefer downhill walks you can take the train up and trek back down, or you can do a complete loop lasting approximately 4.5 hrs.
The Mer de Glace is famous world-wide and is the longest glacier in France. The hike up to it is steep in places but not too tricky for anyone with a reasonable level of fitness.
There are plenty of places to stop and catch your breath en-route, as well as a little refuge where you can stop for a drink and a look at the incredible view.
This hike can be done as one big loop or, thanks to the Montenvers train, you can either do the ascent or the descent and ride the train in the other direction.
Worth knowing
The Mer de Glace was featured in Mary Shelley's famous novel "Frankenstein", as being where the monster hid out amongst the ice.
Watch out for
If you hiking in May or September, be aware there is likely to still be snow on parts of the trail. Check conditions before you go and if you don't have the right gear / footwear, don't risk it.
