Watch Coast Season 6 in Australia

The latest adventure begins in the historic heart of London, continues along the south coast of England and out across the channel to explore the curious coast of Belgium. Nick Crane discovers why the world's biggest cargo ships are on course for London before crossing the channel to Belgium; he rides one of the longest tramways in the world, and investigates how a beautiful seaside resort became the base for Albert Einstein's battle against Nazi tyranny. Neil Oliver reveals the remarkable tale of Hitler's audacious gamble in 1942, when his biggest battleships steamed straight along the English Channel in broad daylight. Alice Roberts uncovers the surprising story behind the rise and fall of the seaside landlady. In the fabulously preserved medieval city of Bruges Mark Horton unearths why our ancestors came there 700 years ago to re-discover the forgotten art of making bricks. Plus, Miranda Krestovnikoff is on the Belgian coast to meet the last few men who still use heavy horses to fish for shrimp.

The team's journey continues around the stunning shores of Devon and Cornwall. Nick Crane is on a fishing expedition on board one of the last remaining Brixham trawlers. He also explores how Henry VIII, fearing attack after his famous divorce, built a string of cleverly positioned forts all along the south coast. The Isles of Scilly are surrounded by lush, golden green underwater meadows of seagrass; Miranda Krestovnikoff explores the diverse wildlife of this natural sub-sea paradise. Mark Horton reveals the extraordinary story of how Lawrence of Arabia went to Plymouth, where he helped develop revolutionary fast rescue boats that saved countless lives in the Second World War. Dick Strawbridge learns the surprising secrets of the global steam power revolution pioneered in the tin mines of Cornwall some 200 years ago. And with the aid of some big wind machines, Alice Roberts creates her own perfect storm.

Coast ventures out to brand new territory, the astonishing man-made shoreline of the Netherlands. Nick Crane explores how ingenious Dutch engineers created massive coastal defences like no others on earth following the great North Sea flood in 1953 which killed thousands of people in the Netherlands and Britain. Nick also discovers how, during the Second World War, traitors from the British Indian Army took part in the Nazi occupation of the tiny isle of Texel - the unlikely site for the last battle in Europe of the Second World War. Coast newcomer, historian Tessa Dunlop, is on the trail of Tulipmania, the extraordinary trade in tulip bulbs that's said to have nearly bankrupted the Dutch nation nearly 400 years ago. Mark Horton reveals the age old skills that have made the Dutch the Grand Masters at creating new living space from the sea. Adam Henson, himself a farmer, investigates why cows from the coastal plains of the northern Netherlands became the most sought after milk producers in the world, and one of the most familiar sights in the British countryside. Miranda Krestovnikoff experiences how the Dutch delight in devouring raw herring as a sea side snack!

Coast embarks on an island-hopping adventure in Scotland around the stunning Western Isles and out to the northern outpost of Shetland. On Eriskay, Nick has a close encounter with a family of dolphins and he is invited to a golden wedding anniversary where the whole island gather to party. On the Isle of Lewis, Nick meets the leader of the Guga Hunters, a small band of men following the age-old tradition of catching young gannets. Neil Oliver explores the tragic shipwreck of the Iolaire. On New Year's Eve 1918, over 200 servicemen returning home from the First World War, drowned within sight of their homes on the Isle of Lewis as the Iolaire was torn apart in ferocious seas. Hermione Cockburn is on an expedition to Staffa. Armed with an acoustics expert, a violinist, and a starting pistol, she conducts a curious experiment to explore the remarkable musical quality of Fingal's Cave. Miranda Krestovnikoff is on Shetland to search for the shy otters who struggle to survive on this wild coast. Tessa Dunlop is on a deep-sea survey ship to see how the epic voyage of HMS Challenger first revealed the astonishing secrets of life in the depths of the world's oceans.

Coast travels right around the wonderful Welsh coast from the Severn estuary, to the Dee estuary. Nick Crane investigates the evidence that a devastating tsunami crashed on to the coast of Wales and England some 400 years ago. Villages were wiped off the map and thousands died, leaving the survivors to believe they had suffered the judgement of God; but was it a tidal wave that was to blame? Nick also discovers why scientists planning an expedition to the Red Planet find the Welsh coast a surprisingly good stand-in for the surface of Mars. Alice Roberts attempts to get airborne with just helium balloons attached to her waist as she tests the claim that the world's first powered flight was actually made by a Welsh carpenter. Meanwhile, Miranda Krestovnikoff lands where few people ever tread - on Grassholm; an extraordinary island normally kept exclusively for the birds. In 1947 two brothers were on holiday on Anglesey when one sketched a rough notion in the sand for a completely new kind of vehicle - Dick Strawbridge explores how that coastal blueprint became the plan for the Land Rover. Plus Tessa Dunlop reveals how some 30 years ago an army of local volunteers managed to keep 3,000 Asians, who had been expelled from Uganda, warm and well-fed in an abandoned military base during a Welsh seaside winter.

For centuries Britons have charted a course to the glorious coast of Sweden for its treasure trove of riches, now for the first time Coast explores the British connections to this stunning shore on the edge of the Baltic Sea. Nick Crane's journey starts in one of the most picturesque parts of Sweden, the dramatic peaks of the High Coast are a wonder of the world and, remarkably, the mountains are still growing at the rate of one centimetre every year. Nick also finds out why Britain's early engineers had to come to Sweden for iron to help forge our Industrial Revolution. Alice Roberts explores the extraordinary story of how, during the Second World War, Britain's military effort almost ground to a halt without Swedish ball bearings and how brave British servicemen beat the German blockade of the country. Mark Horton visits the world's most remarkable shipwreck, The Vasa, which has been called the Tutankhamun of maritime archaeology. Dick Strawbridge climbs the rigging of one of the last great commercial sailing ships, known as the Windjammers. As recently as the 1940s these tall ships managed to give steamships a run for their money. Dick discovers how in the days of Empire, the Windjammers connected Britain to Australia with their legendary grain races. The team also explore Abba Island and search out moose in Sweden's frozen North.
