In the final episode of the series, Penelope travels coast to coast across the stunning Welsh peninsula of Pembrokeshire. Although remote, this area is nonetheless a magnet for fascinating villages, clinging to cliffs and estuaries, or nestled beside beaches, farms and castles. Penelope visits Manorbier, with its tea shops and connections to both Virginia Woolf and Narnia. Then it's the waterside villages of the Cleddau Estuary, from Llangwm to Lawrenny. In the wild Preselli Hills to the north, Penelope encounters the Welsh-speaking villages of Cwm Gwaun and Mynachlogddu. There is also St Dogmaels, home of one of Britain's best food markets, and Abereiddy, one of the venues for the cliff diving World Series.
