Max divers per trip: 5

Dive in The Wormhole. The ‘hole’ has been described as a wonder of our world.

Near the spectacular Dún Aengus fort is a strange geological phenomenon called the Wormhole (or Poll na bPéist). The Wormhole, (perhaps so called because ‘serpents’ - possibly Basking Sharks - sometimes get trapped in it between the tides, or because it is a "puffing hole" where the incoming swell forces up plumes of water, like from a spouting whale) is an almost perfectly rectangular pond created by a huge slab of limestone either being eroded from beneath or falling out to leave a hole approximately 30m long by 10m wide and, by legend, of unknown depth.


To dive in The Wormhole, you must have Advanced Diver qualifications (or equivalent). If you haven’t dived in over 12 months, we highly recommend the Scuba Reactivate program before booking a Dive Trip with us.
