Coastal Adventures with Helen, Jules & JB

JB Gill explores the Sussex coast in Brighton, home to beach huts, saunas and the i360 - Europe's tallest moving observation tower. In Merseyside, Helen Skelton joins the crew of the RNLI's high-speed Shannon lifeboat. Jules Hudson visits the Portsmouth Historic Dockyard on the Dorset coast, uncovering a personal chapter of naval history and tracing the story of his great-uncle George Norcott.

In Anglesey, Jules Hudson explores the site of a 19th-century shipwreck near Moelfre, where over 400 people perished. Helen Skelton learns about the women who helped win the war - not in factories, but in shipyards - in Sunderland. JB Gill begins his journey at Mersea Island Vineyard, where he's introduced to a surprising local speciality - beer brewed with oysters.

On the Lancashire coast, Helen Skelton heads to Fleetwood's Rossall Coastwatch Tower, where she joins the local National Coastwatch volunteers to learn the skills needed to keep eyes on the water. JB Gill explores the cliffs of Porthcawl, South Wales, where layers of ancient limestone reveal a forgotten prehistoric world. In Dorset, Jules Hudson musters his courage for a paragliding flight above the Jurassic coast.

In southern Cumbria, Helen Skelton takes to the skies in a gyrocopter with veteran pilot Roger to explore a coastline often overshadowed by the Lake District to the north. In Cornwall, Jules Hudson joins marine scientists making waves with a serendipitous discovery - disco scallops. Further up the Bristol Channel, JB Gill faces the Somerset coast at Burnham-on-Sea, where tides race in, and mud flats can trap the unwary.
