The lifeboat, under the command of coxswain Dean Hegarty, launched shortly after 2pm after Valentia Coast Guard radio received reports that a visitor to the island off the Beara Peninsula had gone missing.
Once on scene, the lifeboat commenced a search of the area while Rescue 115 did a sweep of the island and spotted a person who fitted the description of the casualty.
The coastguard helicopter lowered a winchman and confirmed that the casualty was safe and well. All emergency services were then stood down.
Commenting on the callout, launching authority Paddy O’Connor said: “We are delighted at the very swift response of the crew and that the casualty was located safe and well.”
