I would like to make hikers aware that this route can become particularly dangerous in winter, particularly because of the ridge towards the Pas de l'Ane which can become covered in ice. In this case, ice axes and mountaineering crampons are essential. 2 people died at this location on 1/1/2025, which triggered access bans. I have taken steps to have these bans lifted while raising awareness in a constructive way. Take the time to find out about the snow conditions before undertaking this hike. Enjoy your walks!

If instead of staying at the waterfall you go two more minutes you will have a spectacular photo of the Aneto glacier.

Here the valley opens up to reveal a pretty plain. Continue up the valley to Lake Oô, to enjoy more magnificent views.
