Solo. From Eriskay ferry terminal, having crossed as a foot passenger from Barra, walked up road to high point. More or less straight up to the trig point of Ben Scrien and the rocky rib that is the highest point. Down SE slopes a bit and then to Cnoc Pairceanan. Descended towards Loch Cracabhaig and found a gate in the fence. Descended to Pairceanan and continued to Ben Stack.
