The Wormhole (Irish: Poll na bPéist) is a striking natural formation on the western cliffs of Inishmore, known for its dramatic rectangular shape carved into limestone and deep underwater channels connecting to the Atlantic Ocean.
From above, the Wormhole looks like a perfectly framed window to the sea. Beneath the surface, it’s a world of kelp forests, rock formations, and wide open water, a place even experienced freedivers find deeply memorable.
This trip blends freediving with boat access, local knowledge, and careful planning to create a safe, respectful way to visit this remarkable site.
