In reply to crazydaisy:
We're meant to be re-doing the topo for Primel this year.
Most of the topos are available from the local tourist information office (Plougasnou for Primel and Camaret for Penhir).
I remember hearing about some routes having had rockfall at Pen Hir in the spring, but I can't find any info via the CD29. Basically, remember that this is a marine environment that sees a fair battering during the winter, so be careful and use your judgement.
