The obvious hand-crack in the sector, left of an obvious low dihedral.
2 long pitches of excellent 5.7 climbing, then a short, messy, 5.9 pitch to a bolted rappel anchor.
Climbing
5.7 52m. Climb the steep start to the obvious hand crack. Follow this to a bolted belay below a vertical section. Constant at the grade, good rack management is critical.
5.8 43m. Climb a tricky vertical section off the belay past a comfortable dirt ledge. From there, climb the face following discontinued cracks up and slightly left. You will find an old piton coupled with a slightly less old fixed nut. Either build a gear belay here or continue up the intimidating (but no harder than 5.8) roof, to a used-to-be-slung flake. Build a gear belay between the two rooves.
5.9 15m. From the used-to-be-slung flake, climb straight up to a ledge with an unstable boulder to your right. Make a few balance face moves (PG) following the right side of the arete marking the dihedral before the second roof. Traverse left above the corner to an airy, finish over the second roof leading to a bolted anchor.
It might be possible to climb the corner (minimal protection, its left side, or to avoid the roof altogether by going around to the right at the boulder. (Update required)
Originally, P1 was climbed to the dirt ledge, P2 and P3 were climbed as one pitch using careful rope drag management.
Descent
Two 60m+ ropes are required.
Rappel from the fixed anchor straight down to the dirt ledge. Pull your ropes. A bolted rappel station here would help reduce traffic on busy days, as well as make the descent safer.
Walk across the dirt ledge (exposed near the end) to gain slung trees ~5m above the first bolted anchor. Inspect the material
70m ropes: Rappel straight to the ground
60m ropes: Also probably possible to rappel to the ground but available information proposes to do a short rappel to the bolted anchor, followed by a full-length rappel to the ground. (Please update)
Short single-pitch climb that reaches the first anchor of 'Fantaisie Spatiale' and deserves more traffic. Bring small stoppers and Cams under #0.75 for the arch.
5.9 20m: Either climb the starting dihedral of 'Astro' or the left variant of 'Fantaisie Spatiale' into the obvious arch to a bolted anchor.
Finish through 'Fantaisie Spatiale' or rappel down.
