The access is very well signposted, and you can do a lovely loop hike, starting from Saint-Même-le-Haut, or from Saint-Pierre-d'Entremont for the more adventurous. At the end of winter, the water level can be very high.

It is one of the waterfalls of the Alloix, not the highest, but one of the most beautiful.

Magnificent! But be careful on the second part it is much more technical so hiking is ok, running less so :/

Great hike! Make sure you have good shoes with crampons because some slopes are a bit slippery. Magnificent view at the top.

Magnificent and relatively easy pass, with basic fitness. Offers a magnificent view of Mont Blanc. Be careful though, the Chaos and the Col are currently completely covered in snow. Being in a group, I did not attempt the ascent of the Col which, without equipment, can be particularly slippery and dangerous. Possibility of going back down via Prayet towards Saint Pierre en Chartreuse. Tested in November, however, no problems observed, very accessible.
