Departing from the pier at Oughterard, this company's sightseeing boat cruises across Lough Corrib, Ireland's largest lake, stopping at some of its 365 islands. One visits Inchagoill Island, with its 12th-century monastery that was inhabited until the 1940s. Another trip goes to the island and to Cong in County Mayo, site of Ashford Castle. The Cong-Oughterard round-trip cruise can start at either place. In fact, there are currently four different day cruises on offer, as well as an evening "Irish Hour" (happy hour) cruise.
