class="content__text" Although you’ll often hear it referred to as ‘the Serpent’s Lair’ and ‘ #TheWormhole’, the official name for one of the most unique attractions on the #AranIslands is ‘Poll na bPeist’ 🐍🐍 You’ll find Poll na bPeist around 1.6km south of the magnificent cliffside fort of #DunAonghasa, on the west side of #InisMor Island 🗺️ Although the finely-cut edges would lead you to believe that this is a man-made swimming pool, it was in fact formed naturally 😯 Poll na bPeist has a number of underground channels which connect to the ocean. When the tide is in, water rushes into the hole via an underground cave and forces the water over the edges, filling the hole from above 🌊 Although you’ll see pictures online of people swimming here, it’s STRONGLY advised that you avoid entering the water at Poll na bPeist ⛔️ Footage licensed through Shutterstock #TheIrishRoadTrip
