0°C at 2900 meters, no snow or ice in the canyon. Bridges were removed for winter, so we chose to start at the right section ('bras central'). Anchors are of good quality. Mostly single bolts; high rappels with double bolts. We did the C56 with the D7 and D48. Tricky (but not too hard) to reach the anchor of the D48; and easy to spot from above. With a 50m rappel rope we barely made it to the ground (the last person ended up 2 meters above the ground). We would advise to take a longer rope (55+m). Most bolts are well placed so you can stay clear of the water. Siphons were not a problem, easy to shunt or go through. Beautiful and impressive trip!

Viewed from downstream when accessing III.

First part dry, but each affluent privided a small amount of water. Few new bolts. Most anchors only one bolt, but in good shape and well placed considering the line to rappel. Some anchors placed considerably high, but were reached quite easily. Exit ropes in place (see photo; although we did not use them as we continued IV).

Acces ropes in place (although we accessed it by doing III). Few new bolts. Most anchors only one bolt, but in good shape and well placed considering the line to rappel. Some anchors placed considerably high, but were reached quite easily. No ice or snow.

Low water level, fair anchors. Some webbing is a bit old, but doable. Some of the small rappels can be climbed down.

Good anchors; first C8 after the 100m walk is one very difficult to reach bolt, but there is alternative natural anchor on the right side. Foto: normal water level at the start of the canyon.

Good water level, very cold. Anchors mostly okay; the plate of the mono anchor C13 is a bit loose.
