In reply to jcw:
> Yep, but looking at the boundaries of Choranches they do not seem to impinge on the Presles access.
Well yes they do. The only way to the bottom of the crag ON FOOT is wholly in the commune of Choranche. True, if you park on the plateau and approach the top of the crag via one of the maze of footpaths up there, then you are in Presles but you have to then locate the top of your route (or an abseil piste) and abseil down to the bottom of the crag. Locating your route of choice - especially for first time visitors - is not easy. However, glasgowcaver's last paragraph is rather worrying:
> If you look at the first two comments on the petition (most liked) you'll also see that there's a history of bad behaviour and bullying in this commune. Incidentally there have been landowner problems at the top of the cliff as well so don't assume Presles is exempt - and there is at least one landowner who owns land up at Presles as well as Choranche.
