Ireland

The world's second-largest fish visits Irish waters in late spring to feed on plankton blooms; a breathtaking sight for divers and snorkelers.

Ireland, the 'Emerald Isle,' offers some of the most spectacular and rewarding temperate water diving in the world. Its rugged Atlantic coastline, shaped by powerful swells and the warming influence of the North Atlantic Current, is home to an incredible diversity of marine life and dramatic underwater landscapes. Jacques Cousteau himself famously remarked that some of the best diving in the world is found off the coast of Ireland. Divers are drawn to the wild beauty of the west coast, from the towering cliffs of Donegal and the clear waters of Galway to the world-class sites around the Skellig Islands and the Beara Peninsula in the southwest. The underwater world of Ireland is a vibrant tapestry of lush kelp forests, jewel anemone-covered walls, and a wealth of historical shipwrecks, including those from the Spanish Armada and both World Wars. Marine life is abundant, with frequent encounters with grey seals, dolphins, basking sharks, and a kaleidoscope of colorful invertebrates. While the conditions can be challenging, requiring drysuit proficiency and a respect for the Atlantic's power, the reward is a truly wild and exhilarating underwater adventure that perfectly captures the untamed spirit of Ireland.

While most diving in Ireland is land-based, there are occasional liveaboard expeditions, particularly around the remote islands of the west and for exploring the deep-water wrecks off the north coast.

Renting a car is the most effective way to explore the rugged west coast where the best diving is located. Ireland has a reliable train (Iarnród Éireann) and bus network (Bus Éireann) connecting major cities.
