About 20 years ago, we spent three days (very sporadically) searching for Le Cube - never found it, although my guess is that we got top within 300 yards. Turned out the French couldn't find it either!
Instead we found a lovely little crag in the vicinity, called L'Imperatrice (or summat like that). Back then, was half-trad, half-sport. Being lazy, we ticked the latter. Nice views of Brest and a belt of overhangs which you could yard through on jugs/flatties at never more than about F6c.
Caveat: a long time ago, failing memory, things may have changed. But we thought it better than Pen-Hir.
