Eas a' Chual Aluinn

Eas a' Chual Aluinn in the parish of Assynt, Sutherland, Highland, Scotland, is the tallest waterfall in the United Kingdom with a sheer drop of 200 m. At full flow, is nearly four times taller than Niagara Falls.

The waterfall can be reached by a 6 mi walk across boggy ground from the road 3 mi south of Kylesku in Sutherland. In good weather, a boat-trip runs from the slipway by the Kylesku Hotel to Loch Beag, from where the waterfall is visible.

The name is a corruption of Eas a' Chùil Àlainn, ("waterfall of the beautiful tresses").
