In a fertile valley between Glendalough and the Vale of Avoca, this is the former home of Charles Stewart Parnell (1846-91), one of Ireland's great political leaders. Built in 1779, the house is now a museum dedicated to his memory. The parkland around the house is beautiful, with wooded nature trails along a river, and more formal gardens near the house. There's a cute cafe serving tea and light lunches, as well as homemade breads and pastries, and there's also a playground for children, which should keep them busy for a while. The house's opening hours change regularly, so give them a call before you go.
