Glas Bheinn
Glas Bheinn — the Grey-Green Hill — sits at 562m on southern Jura just inland from the Sound of Islay. Quartzite slabs catch the light from miles away, lending the hill a paler, almost alpine look amid the heather wilderness.

Standard route
quartzite moorland 45% · heather moorland 35% · boggy ground 20%
Begin from the A846 near Keils and follow open moorland north-west, gaining height steadily over awkward ground. The summit lies on the third or fourth false top. Round trip 5-6 hours.
Terrain
Pale quartzite scree and slabs above; deep heather and bog below. Some of the scree shifts underfoot and demands care on descent.
In winter
Snow flecking the quartzite slabs is unusual but striking when it occurs. Winter access is feasible in calm weather; gales make the exposed upper slopes uncomfortable.
