Sheltered from prevailing winds, Cwm-yr-Eglwys is renowned for having its very own microclimate, it being a few degrees warmer and dryer compared to other parts of the Pembrokeshire coast. This allows the growth of trees and shrubs of almost Mediterranean luxuriance.
I find this difficult to believe as you don’t find many swimmers in the Mediterranean, choosing to wear wet-suits on their summer swims; they are not rare in Cwm yr Eglwys, however.
Maybe the trees along the cliff-tops do give this bay a rather Mediterranean feel. If you’d like a reminder of the real thing, here is a water colour by local artist, Jean Pugh. It’s entitled Pine trees / mountain, Aix en Provence and is on sale at Len Rees’ beautiful Gallery* for £250.
