This is an easy slab climb with great views.
I wouldn't recommend it if you don't have much time, since there are much nicer climbs that are a little bit harder. It is great for novice leaders or to take a novice 2nd.
Head ENE (right if coming up from Tré-le-Champs) along the climber's access trail located off of the main hiking trail. The climb starts at the base of a rounded slab-like pillar. Von Kanel's "Plaisir West" has a good access drawing.
Well bolted climb with anchors at the top of each pitch. Bring 10 quickdraws. Rappel from the top in three 50-meter rappels. As with many climbs in the area you'll need double ropes. I've heard that you can continue up from the top and walk off, but this would be quite long to get back to the base of the climb.
