Coire Gabhail

Coire Gabhail (Corrie of the Bounty, or The Hollow of Capture) is a high level glen in the Bidean nam Bian mountain massif to the south of Glen Coe, Highland, Scotland. Its narrow entrance 230 metres (750 ft) up the hillside conceals the width of the glen beyond, and it is commonly known as the Hidden Valley or Lost Valley of Glencoe. Access from a bridge crossing the River Coe is by a steep path up beside a narrow wooded ravine.

The valley of Coire Gabhail runs southwestwards between the steeply-sided ridges of two of "The Three Sisters"; on its left, Beinn Fhada (Long Hill) is the eastmost sister, and the central sister Gearr Aonach (Short Ridge) on the right of the valley forms its western side. Further to the west of Gearr Aonach, Coire nan Lochan is enclosed by Aonach Dubh (Black Ridge).

The southern end of Coire Gabhail is marked by the peak of Stob Coire Sgreamhach on the ridge which then slopes down westwards to its low point at Bealach Dearg, then continues up above cliffs to the summit of Bidean nam Bian.
