Couldn't get the link to work but it sounds like West Penwith. Lands end long route (lands end), commando ridge (bosigran) and a few routes at Sennen are all used by the marines.
I only skimmed through it but bits I saw were lands end and bosigran. I know that area so if you want specific route names ect then just tell me what time they're at and I'll have a look.
