Desert Shores, Deep Mines & Wind in Your Wheels

The coastal adventure kicks off along three very different, dramatic coastlines, as Helen, JB and Jules explore glorious landscapes, underground wonders and meet the fascinating people who know all the secrets.

In North Yorkshire, Helen descends 4,500 feet into the UK's deepest mine - an extraordinary undersea world and the only place on Earth where Polyhalite is extracted. She gets a real taste of mining life: a creaky lift ride, 35-degree heat, and the rumble of a multi-tonne mining machine. Back on the surface, she swaps drills for thrills, meeting a Redcar land sailing legend and joining the wind-powered action on the beach. There's even time for a Teesside classic - the Parmo. Chicken, béchamel and cheese? Yes please!

Down on the Kent coast, JB explores the strange beauty of Dungeness - a vast shingle headland and a haven for unlikely wildlife. From laughing frogs to leeches he discovers just how wild Britain's only desert can get. At Broadstairs beach, he meets heroic rescue dogs whose super-snouts are saving lives along the shore.
Meanwhile, Jules is in Devon, setting sail from Salcombe aboard the iconic Yawl - the pride of the south coast. Then it's into the depths of Beer Quarry Caves, a sprawling labyrinth hand-carved over 2,000 years. Among the Roman coins and medieval carvings, he stumbles across something unexpected: a local male voice choir, drawn here not just for the history, but for the incredible acoustics – the best in the country!

And while they may be hundreds of miles apart, the banter's never far away as Helen, JB and Jules share all their adventures with each other.
