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.

Key hazards

  • very cold water year-round
  • boulder scramble approach requires care
  • high flood risk after rain

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.

Best for

  • adventure dip
  • Glencoe Munros combination
  • dramatic mountain photography
