Brings you the best marine ecotourism experiences in Europe

County Donegal is a largely Irish-speaking region bordering the Atlantic Ocean in northwestern Ireland. It’s known for its castles, rugged coastline and mountains such as the iconic, quartzite Mount Errigal. And most recently, for being chosen as The Coolest Place on Earth by National Geographic.

Formerly a private estate, Glenveagh National Park encompasses forests, lakes and bogland in the central Derryveagh Mountains. Its 1870s manor house, the Scottish Baronial-style Glenveagh Castle, is renowned for its Victorian-era gardens.

Donegal's coast is home to an impressive and rich variety of marine wildlife. Sea birds, cetaceans, seals...they are all part of its beautiful, natural landscape. But if anything makes Donegal a reknown place for marine researchers from around the world - and for wild watching holidays and ecotourism adventurers alike - that is its international relevance as a hotspot for sharks. One particular species is king in this realm for the curious visitor: the basking shark.
