This small 2 person chair lift is only open for a short time in summer, but it's great if you want to take a close up look at the bottom of the Glacier des Bossons.
The lift takes you to an altitude of 1,425m and conveniently to Chalet buvette du Glacier where you can stop for refreshments and get some great views of the bottom of the glacier. At around 7km long this is one of the longest glaciers in Europe and because it travels so far down the mountain, you can see it from pretty much everywhere in town.
From the chalet at the top of the chair lift, you can take the un-guarded hiking trail up to 'Les Pyramides' and at the very top, 'the Junction' where you will be surrounded by glaciers. Be warned though it's a tough slog up and back down again, and can take the better part of a day to complete.
