15m, 2 pitches. The description for this route in the 'current' guidebook (SD&D) is written in a mixture of Italian, German, some form of ancient Greek and Hebrew.
"As is usual now start at the bottom of the seaward side.
1. 30 feet. Go up a steep wall, nail for aid (!) and move left onto a big ledge and belay.
2. 20 feet. Take the corner to the top."
