Hear pronunciation Press to hear pronunciation

Compared to their illustrious neighbours on the eastern side of Arran, the Pirnmill hills are unfrequented and unassuming. However, a round of these hills provides a very enjoyable day with fine views. Notwithstanding the OS map, Beinn Bharrain is the name of the whole hill, with Mullach Buidhe the highest of its summits.


Boggy approach path. Some tricky scrambling on the ridge, but this can be bypassed. Straightforward hillwalking on the tops, with a good path on the final descent.
