Wonders of the Coast Path

The first leg takes Sean along the coast of north Wales and on to the island of Anglesey. Along the way searches for 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 Llŷn 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 week Sean travels down beautiful Cardigan Bay, where he helps monitor the local dolphin population, discovers a four thousand year old sunken forest on a beach and takes part in a Celtic Longboat rowing race.

This time, in Pembrokeshire, Sean meets a family who have moved to the coast to live off-grid and takes part in an archeological dig to unearth the secrets of a medieval chapel. Then he joins members of a Blind Society to find out how they use sound to experience the coast and discovers baby seals at Castlemartin military firing range.

Sean Fletcher's walk around the Wales Coast Path reaches Carmarthen Bay and the Gower Peninsula, an area known for its peaceful estuaries, sandy beaches and limestone cliffs. At Pendine Sands he hears the story of Wales' land-speed record holder and sees his original car roar up the beach once more. Sean also tries to beat the tide and reach the end of Worm's Head, the westerly tip of Gower.

Sean Fletcher is on the final leg of his epic journey along the Wales Coast Path, exploring the sand dunes at Merthyr Mawr on horseback. He discovers how sea cliffs breathe in and out with the pounding of waves and re-creates Marconi's first radio transmission over open water, from Lavernock Point to Flatholm island.
