Many of you are familiar with the Mer de Glace and its trusty red cogwheel train. This time, however, you won't be using the train - you'll be climbing Mer de Glace on foot. Don't worry, you'll be able to admire the little red train as you make your way up. The hike continues as far as the ladders leading down to the Mer de Glace. From here on, the ride becomes mountaineering, and it's time to turn back.

A high-level and stimulating walk along the Grand Balcon Nord overlooking the Chamonix-Mont-Blanc Valley. The route starts from the Montenvers train station (the Little Red Train) and passes the Refuge du Montenvers (worth an overnight stop). The Grand Balcon Nord terminates at Plan de l'Aiguille but the route drops down to Les Houche on the river L'Arve to reach the Chalet Les Méandres (ex Tupilak).
