County Londonderry

County Londonderry (officially Derry/Doire and commonly referred to as Derry) sits on the north coast of Northern Ireland facing the North Atlantic. The region is primarily inland in terms of diving relevance, with limited saltwater dive options concentrated along the coast near Portstewart and in the nearby inner seas off the west coast of Scotland. Freshwater bodies like Lough Neagh provide non-coastal water experiences but are not typical dive sites. Overall, the area's diving character is modest, with few readily accessible dive sites within administrative boundaries; most divers visit from neighboring coastal counties for coastal/plain dives or travel to more established diving hubs in Northern Ireland or the Republic of Ireland.
