Diving in Ireland is relatively unknown to the international community, but take the underwater superhero Jacques Cousteau’s words: “Some of the best diving in the world is at the northern side of the Dingle Peninsula where the Atlantic Ocean meets the Brandon Mountains in a landscape of exceptional beauty.” This is descriptive of the underworld in Ireland. Apart from the magnificent underwater scenery, the gulf stream and warming the sea brings nutrients to Ireland, resulting in the unique and abundant marine life. From small fish like lings and sunfish to massive creatures like whales and basking sharks.
