Step aboard Blacksod Sea Safari's 33ft passenger boat, The Huntress, and explore the delights of Blacksod Bay in Mayo from the water. There's so much to see, from the impressive Cliffs of Croaghaun to the deserted village on the Inishkea Islands, uninhabited since the 1930s. And between them, there's plenty of marine wildlife to spot along the way, including seal colonies and the birds of Duvilluan.

There's also tours of Blacksod Lighthouse, from which Maureen Sweeney's fateful weather forecast determined the exact timing of the D-Day Landings of June 1944, and dedicated angling trips of the bay, which is home to mackerel, wrasse, ray, monkfish and a host of other fish.
