Northern Snowdonia: Kate and Teg travel from the most northerly farm on mainland Wales, just outside Llandudno, across to the sleepy hamlet of Nantmor in Snowdonia. Along the way they experience the comeback of old-style shepherding, learn how canine power is saving lives on the mountains, and see a forest through the eyes of a pack of huskies--before she skinny-dips in a freezing lake.
