Eoin begins on the Skellig Islands off the Kerry Coast, surrounded by thousands of comical puffins and secretive shearwaters who travel to Skellig from sub-Antarctic waters every year to find the same nest to breed.
Eoin explores the sheltered Conamara Islands before heading north for Mayo to encounter some of Ireland's hardiest long distance travellers - the whooper swans who arrive out of the north every autumn. We go underwater to meet the basking, who now thrive in Irish waters after years of persecution came to an end.
