Glas Bheinn
Glas Bheinn on Islay is the close neighbour of Beinn Bheigier — a 472m hill on the same wild eastern moorland. Its limestone-influenced geology gives surprisingly green, drained turf in contrast to the boggy approach.

Standard route
limestone grassland 40% · heather moorland 40% · rocky outcrops 20%
Often combined with Beinn Bheigier from Ardtalla, taking the ridge link between the two summits. As a stand-alone ascent allow 3-4 hours. There is no path either way.
Terrain
Surprisingly well-drained turf on the upper slopes thanks to the limestone bedrock. The approach moor is wetter and tussockier.
In winter
Snow is unusual on Islay. The bigger risk is high wind on the exposed upper ridge — gales of 60mph are not unusual in winter and make the summit untenable.
