Out for a post-Easter walk we came across a most charming small natural seawater pool just off Menabilly beach. At about four metres by three metres and perhaps just under a metre deep, it hardly qualifies to stand alongside the other great pools around the coast but it appears to be completely natural and was filled (at a very low tide) with water so clear that it was difficult to see the surface.

Part of its charm is that it is set within a single circle of rocks which appears crenellated like a miniature castle, almost as though the mermaids had created their own small pool. Many of the larger pools, such as that at Boat Cove, Pendeen, seem to have their own ‘children’s’ pool. Here is one on its own.

You can find it here (if the tide is out)
