Ellie and Steve are on the Llyn Peninsula in north west Wales. Ellie goes snorkelling to explore the rich seagrass habitat beneath the waves, before joining the conservationists netting fish as part of a marine survey. She also meets 19-year-old Urien Davies-Hughes, a third-generation boat builder who uses his grandfather's tools to build traditional Aberdaron beach boats. Steve meets the dairy farmers who both produce and deliver their own milk. He also visits the farmers who have turned their hand to bespoke ice cream and comes up with a brand new flavour of his own. Adam takes part in a mulberry harvest, while John is joined by fellow judges Simon King and Deborah Meaden to reveal the final 12 photographs in this year's Countryfile photographic competition.
