With visibility averaging 15m (49 ft.) and occasionally reaching 29m (95 ft.), and many wrecks to explore, the west coast of Ireland may be cold, but it's still a pretty good place for divers.

The Irish dive season generally starts in March and ends in October, although specific dates depend on your comfort zone. Outside these months, weather and ocean conditions could make jumping into the sea unappealing. The PADI open-water diver certification is the minimum requirement for all dives; most schools also offer introductory dives for novices.

The rocky coast of West Cork and Kerry is great for diving, with centers in Baltimore and Dingle. On the west coast, there are many great locations, one of which is the deep, sheltered Killary Harbour. Northern Ireland offers many interesting dives, with more than 400 named wrecks off the coast and many in the Irish Sea and in Belfast Lough.
