Beinn Tart a' Mhill
Hill of the Thirst, the high point of the Rinns of Islay peninsula in the far west of the island. A trig pillar crowns the summit and the open situation gives a remarkable horizon for so modest a height — Jura, Colonsay, the Antrim coast and the open Atlantic all in view on a clear day.

Standard route
heather and bog 60% · rocky slopes 25% · coastal grass 15%
Most parties start from the Portnahaven road and pick a line up the rough heather slopes from a layby near Loch Gorm. There is no path of any note and the going is wet — give it three hours round trip and accept boggy boots as part of the experience.
Terrain
Trackless heather and peat hags across the Rinns plateau. The summit area is rocky but the approach is the wettest part — wet feet are almost guaranteed after rain.
In winter
Mild Atlantic winters mean genuine snow cover is rare, but gales sweep the Rinns from October through March. Visibility can drop to nothing in driving rain — a compass is essential off the road.
