At Rossaveal, board a comfortable, modern FERRY for the 45-minute crossing to Kilronan on Inishmore, the largest of the Aran Islands and where Gaelic is the first language of the islanders. Many Catholics fled to this island during Oliver Cromwell’s conquest of Ireland during the mid-17th century. In these harsh conditions, they developed a strong self-sufficiency in order to survive. Your fascinating day continues with a presentation on life on Inishmore by an island historian. After a lunch break, board a minibus to enjoy your driver-Local Guide’s commentary on a tour of the island, ending with a visit to clifftop DUN AENGUS, one of the most spectacular and dramatic prehistoric stone forts in Europe. Back in Kilronan, board your ferry for the trip back to the mainland. There are plenty of dining options in Galway this evening. (Breakfast)
