In reply to Exile:
Not sure how easy it is to get the guide but I would have thought it was available. Certainly the bar in la Hermida sells the Hermida guide and may well have the big Roca Verde guide too.
I suggest you email Richie Patterson via the Roca Verde webpage and ask him. He wrote the guides and will certainly know. Or if you have time, order a guide via the webpage. Its a great guidebook.
