He was body bording at the time of the incident in Ballard Bay near Doonbeg, close to a world famous surfing spot called ‘O’Reilly’s Wave’.
The 34 year old suffered a suspected broken leg.
A number of other body boarders and surfers helped him from the water and onto the rocks while the alarm was raised.
Valentia coastguard received the call at 9:44 this morning and tasked the Shannon helicopter, Rescue 115.
The man was then airlifted to University Hospital Limerick for Treatment.
