Smoo Cave

A huge cave at the head of a narrow sea inlet on the edge of Durness, its first chamber carved by the sea and its inner ones by a river falling through the roof.

Welcome

On the eastern edge of Durness, a narrow, steep-sided inlet cuts a third of a mile into the limestone cliffs, and at its head yawns the great mouth of Smoo Cave.

The name may come from the Old Norse for a hiding place, and the Vikings did use it: traces of a fishing and boatbuilding community have been found here.

Steps lead down the side of the cleft from the car park, and a footbridge crosses the river to the entrance. The first chamber is huge, some 200 feet long and 50 feet high at the mouth, and it was carved by the sea. What makes Smoo unusual is what lies beyond: the Allt Smoo drops into a sinkhole on the far side of the road and pours through the roof into an inner chamber in a roaring waterfall, and it is this river that hollowed out the cave's inner rooms.

The cave can also be explored by boat, for a closer look at the inner chambers.
