The Barranc de l'Avern is a deep-cut twisting ravine with a lot of exposed rock and a busy road running through it. If it wasn't for the road it would be an extremely pleasant location but even with this drawback it is still a worthwhile venue for middle grades climbers. The rock is good and the climbs tend to follow vertical walls with some featuring small overlaps. The gear is a bit old on some routes however there is some replacement going on.
If the main gorge is a bit too noisy for you the Sectors Deposit and Visera should suite; they have an idyllic setting in a secluded valley, hemmed in by the hills and are a complete contrast to the other cliffs here.
