Allt Coire Gabhail — Lost Valley
The Lost Valley (Coire Gabhail) is Glencoe's hidden hanging valley — the MacDonalds' cattle corrie, concealed behind boulders and entered by a narrow gorge. The Allt Coire Gabhail stream that threads through it cascades in cold, crystal-clear pools between huge boulders. This is not a swim for distance — it is a cold-plunge in one of Scotland's most dramatic mountain environments. The approach from the car park is a steep mountain path with rough, rocky sections where you need your hands.

Getting there
Car park on the A82 below the Three Sisters in Glencoe. Follow the Lost Valley path — the rocky sections require hands. National Trust for Scotland land; access rights apply.
Safety
The pools are shallow and boulder-strewn — this is a dip, not a swim. Very cold even in late summer. The approach needs confidence on steep, rocky terrain, and the path crosses the burn. Never attempt in high water or after heavy rain.
