Is there such a thing and if so how do I get it?
I have rockfax guides to some Scottish Crags but these are very limited
Rockfax doesn't actually produce any guidebooks to Scotland. We do have a great working relationship with the SMC which means that they are able to use Rockfax Digital for their guides.
There are a couple of guidebooks listed here - https://www.ukclimbing.com/logbook/crags/carnmore_crag-777/#guidebooks
That also says that Carnmore is on Rockfax Digital. This is a bit of a drawback with our system since it is actually being triggered by the one scramble Grey Ridge (Grade-3) and in fact, the climbing hasn't been added to the app yet.
This is the comprehensive guidebook to Carnmore - http://www.smc.org.uk/publications/climbing/northern-highlands-central it includes all the routes done up until 2006. However this book covers all the popular classics http://www.smc.org.uk/publications/climbing/scottish-rock-climbs
