Ben Oss and Beinn Dubhchraig, near Tyndrum

Hear pronunciation Press to hear pronunciation

Ben Oss and Beinn Dubhcraig are satellites of mighty Ben Lui. Although the mountains themselves are not particularly distinguished, the approach walk leads through natural pine and birch forest and is very picturesque, though also very wet. Beinn Dubhcraig offers a fine view down Loch Lomond, whilst the Ben Lui looks simply magnificent from Ben Oss.


Extremely boggy path on the lower approach. Higher up the going is drier; the ridges are broad but rocky and undulating and with some crags - can be confusing terrain in poor visibility.

Public Transport

None. Nearest is train and bus at Tyndrum which is 2.5km walk on WHW.


Dalrigh. Open start point in Google Maps for directions.
