There are roughly 6,000 islands in the North Atlantic archipelago known as the British Isles. Great Britain is the largest, Ireland the second largest, and there's enough variety in the rest to fill an encyclopedia. But this is the only fjord anywhere among them. This pleasant 90-minute cruise gives you ample time to enjoy the gorgeous views, across glassy waters to the oh-so-green hills that seem to cascade down to the shoreline. Weather permitting, you should be able to see three major mountain ranges: the Maumturk and Twelve Bens to the south, and the Mweelreas in County Mayo to the north. If you’re lucky, as the cruise approaches the mouth of the Atlantic, you might also get to see dolphins. The boat—designed, they claim, to avoid seasickness, or your money back—has viewing decks inside and out, so the tour can be taken in all weathers. A bar and kitchen on board serves sandwiches and light meals, including fresh Connemara oysters. The boats depart from Nancy’s Point, about 2.7km (1[bf]1/2 miles) west of Leenane (Leenaun).
