Overview:On this Coast journey from Anglesey to Blackpool, Neil is joined by some familiar faces. Nick Crane is seeking out the story of a tiny harbour that played a big part in making a mountain of money at Parys Mountain, and Almwich Port which served it. Hermione Cockburn discovers how postcards from the past reveal a vital message for the future of our seaside in Rhyl, and the history of the Pleasure Beach at Blackpool. Miranda Krestovnikoff is on a sand dune safari in search of creatures great and small. Mark Horton is hunting for the remains of what was once the world's biggest private dock at the site of an early soap manufacture at Port Sunlight. Neil takes a journey of a different kind to the coast about a RAF jet. He also explores a shipwreck that is disappearing before his eyes and sees if he can trace Alice and her wonderland in Llandudno.
