Urchin Cave is a short sea cave on the edge of the Burren near to Doolin town. A short descent down a sheer limestone slab takes you to a low crawl and a small chamber which is dry at low tide.
I tend to find most caves are unique in some way or another, however Urchin Cave is a totally different experience from the rest. There is abundant marine life to be seen and the accompanying sound of waves crashing through narrow side passages, along with the unusual buoyancy and clarity in water is all something not seen in inland caves.
Amongst the organisms I saw on my visit were multicoloured anemones, sea urchins (of course!), a sea cucumber and a number of crabs and fish. The only downside to Urchin is it’s length. In fact it’s so short that we did the trip twice!
