Camas Bhlathain beach, midway between the River Polloch and Eilean Fhianain on the southern shore, it looked very different to when we stopped there in summer a few years ago but still a good spot.
I recognised some of the wider shots, but not the campsite itself. I camped opposite there at the wooded bay to the west of Rubha na h-Airde when I was there a couple of years ago.
Cheers, Michael.
