I had a small topo of one section with grades only. I will share it with you. There was a file with it that I think might have had route names but it is dated 1996 and I can't open it!
It wouldn't surprise me if access was on an ad hoc basis here. At the time I remember it was highly rated crag - "as good as Fraguel" were the rumours. Such is the way with access issues in Mallorca. They come and go, require strange permits for a time, then no-one can be bothered with the permits. My suspicion is that access in very small numbers of locals is tolerated, but anything more than that might cause problems again.
