1 Westport


Westport is a designated Heritage Town on the Wild Atlantic Way and three-time overall winner of the National Tidy Towns Competition, the words picturesque and Westport go hand in hand. The town was the creation of James Wyatt and although classically planned, remains picturesque. Developing from a vision laid down in the 1700’s, Wyatt’s carefully considered plans have seamlessly guided Westport Ireland from the past to the present. This busy little town has a lot to offer whether you are looking for historic tours, scenic walks, gastronomy or bars with entertainment that will take you into the small hours of the morning. Ireland’s Holy Mountain, Croagh Patrick is located just a few kilometres outside of Westport town. The mountain is named after St.Patrick and every year pilgrims make the journey to climb this steep mountain with fantastic views of Clew Bay at the summit.
