Ellie and Steve are on the beautiful Llyn Peninsula in north west Wales. Ellie goes snorkelling to explore the incredibly rich seagrass habitat beneath the waves. She then joins 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 not only produce their own milk, they deliver it too. So Steve's up with the young farmers delivering milk door to door. He also visits the farmers who've turned their hand to bespoke ice cream, and comes up with a brand new flavour of his own. Adam takes part in the harvest of an unusual fruit - the mulberry. And John is joined by fellow judges Simon King and Deborah Meaden to reveal the final 12 photographs in this year's Countryfile photographic competition.
