Offaly is home to some of Ireland’s most fascinating landmarks, including Leap Castle, rumoured to be the most haunted castle in the country. The county also has Clonmacnoise, an ancient monastic settlement along the River Shannon, famous for its round towers and Celtic crosses. If you're after an unusual adventure, the Lough Boora Discovery Park has some pretty striking outdoor sculptures scattered across its boglands. Offaly is also home to the lively Tullamore Show, Ireland’s largest agricultural show, celebrating farming, food, and crafts.
