This morning, enjoy an orientation of the city to see the University of Wales, Principality Stadium, City Hall and the National Museum. Afterwards, join an Optional Experience to Cardiff Castle, a medieval fortress with a colourful history spanning centuries. Ancient ruins and lush countryside lie between the Welsh capital and your first stop in Pembroke. Pass through Carmarthen, the oldest town in Wales and, legend has it, the birthplace of Merlin. See the 11th-century Pembroke Castle, where King Henry VII, the first of the Tudor line, was born, then board your ferry across the Irish Sea to Ireland.
