Sean Fletcher starts his epic challenge, travelling the 870-mile long Wales Coast Path. This first leg of his journey takes Sean along the coast of North Wales and on to the island of Anglesey. Sean goes on a search to find Britain's rarest toad, turns his hand to making a bronze age axe head and has a beach cookout using mussels and oysters caught fresh from the Menai Strait.

The second leg of his journey takes Sean along the Llyn Peninsula in north west Wales. Sean starts his journey at Bangor where he joins the crew of 1930s sailing ship the Vilma to help steer her down the Menai Strait. This narrow stretch of water separates Anglesey from North Wales and has a reputation for being one of the world's most treacherous passages to navigate, with the notorious 'Swellies', a maze of shallow rocks and whirlpools lurking under the surface.

Sean learns about Harlech castle, one of King Edward’s I impressive fortresses along the Welsh coastline.

Sean learns how members of Pembrokeshire Blind Society enjoy the path using other senses on a walk from Haroldstone Chins to Broad Haven.

The fifth leg of his journey takes Sean around Carmarthen Bay and the Gower Peninsula. His journey in south-west Wales takes in highlights from Pendine Sands to Worms Head with stops to collect cockles in Ferryside and a visit to a community project on Gower. Sean's first stop in Carmarthenshire is Pendine beach where he finds out about a legendary land speed record duel between Malcolm Campbell and Welshman John Parry-Thomas in the 1920s.

Sean meets Welsh Opera singer Shan Cothi to take in the beauty of Wales’ highest sand dunes on horseback at Merthyr Mawr Warren National Nature Reserve.
