Siobhán begins by discovering some hidden gems in Co Down. Siobhán follows the footsteps of pilgrims along Saint Patrick's Way, comes face to face with some vicious Vikings, gets a bird's eye view of stunning Strangford Lough and reveals her artistic side with acclaimed artist Colin Davidson. She also samples regency life in an 18th-century mansion, and, in Belfast, conquers her fear of heights at one of the city's iconic landmarks.
