It鈥檚 the bank holiday weekend and millions of us will be flocking to the coast to enjoy the UK鈥檚 beaches, clifftop walks and water activities.

But rising sea levels and the ferocity of the waves put our coastline, its communities and its wildlife under constant pressure, so Ellie Harrison sets off to find out what it鈥檚 like 'living on the edge' of land and sea all year round.

She spends the day on the Steart peninsula on the north Somerset coast to see at first-hand the challenges coastal living can bring. The peninsula itself is home to the biggest new coastal wetland in Britain, marshes created to play a vital role in preventing flooding and fighting the impact of coastal erosion. Ellie finds out how farmland was transformed into a natural flood defence to buffer homes and businesses from rising sea levels, then meets the wetlands trust volunteers who now keep a watchful eye on the wildlife here, as well as the farmers who still manage to make a living from the land.

Internationally renowned wildlife photographer Oliver Hellowell is also on hand to show Ellie how to capture the best view of the marshes. And, down the coast, mud-horse fisherman Adrian Sellick shows how he is keeping a rare coastal business alive in the face of modern challenges.

The programme also looks back at some of Countryfile鈥檚 favourite forays into coastal living.
