Raised beach sea cave.

Cave, may once have contained archaeological deposits, now washed out. [Islay Caves Project]

5 m wide, 1.5 m high entrance. Easy access.

A raised beach cave located at the grassy head of a little shingle cove. Water drips from the rock above into the cave mouth. A steep descent of 7 m over mud and rock debris, leads to a wide, deeply flooded, chamber. On the right wall are several cup-shaped mud nests probably constructed by house martins. The chamber narrows then widens. At about 28 m in, a big roof-fall is encountered with some fallen rock slabs above water level. The chamber is about 15 m wide and the water around and beyond the roof-fall is shallower. On the left of the rock-fall, the still flooded cave extends for about another 10 m until the roof-line drops barring further progress. There are a few colourful flowstone formations, including some rusty stalactites. [Caves of Islay]
