Poll na bPéist
Poll na bPéist, also known as the Wormhole or Serpent’s Lair, is a naturally formed rectangular tidal pool located on the cliffs of Inis Mór in the Aran Islands. Cut sharply into the limestone bedrock, the pool appears almost man-made because of its straight edges and geometric shape. It lies close to the famous prehistoric fort of Dún Aonghasa, sharing the same rugged karst terrain of exposed grey stone, fissures, and sparse vegetation. The pool fills with seawater through underwater channels connected to the Atlantic, and waves can surge dramatically into the basin during high tide. The surrounding cliffs and rock platforms create a striking and exposed coastal environment.
