Kate Humble's Coastal Britain - Season 1

The naturalist enjoys an 11-mile walk in Exmoor along the South West Coast Path, regarded as one of the most beautiful such paths in the world. Starting at Porlock Weir, Kate heads to St Bueno's, a tiny parish church that seats just 33 worshippers - and which holds a dark past. She then heads inland to see the valley that inspired RD Blackmore's 1869 novel of outlaws and revenge, Lorna Doone. At Lynmouth, Kate rides the world's highest and steepest water-powered railway, before finishing her walk seemingly on top of the world in the Valley of Rocks.

On a 15-mile walk in North Yorkshire, Kate sets off from the picturesque settlement of Robin Hood's Bay, where archaeologist Maria explains how, in the 18th century, the fishing village's position made it an idea drop-off point for contraband shipped from Holland and France. From here, Kate heads south along the coast, meeting up with geologist Will, who reveals what dinosaur footprints can reveal about the creatures that once roamed the area. After arriving at her destination in Scarborough, Kate dons her wetsuit to join a group of swimmers braving the North Sea.

From Stonebarrow Hill in Dorset, Kate heads along the coastal path to Cain's Folly, then on to Seaton where she rides a tram out into Seaton Wetlands for some bird spotting.

Starting at Dunwich Heath, Kate walks an 11-mile stretch of the Suffolk coastline - one of the fastest eroding in Europe. The naturalist also finds one of the country's biggest freshwater reed beds, and learns about the ancient art of thatching.

The presenter walks a 13-mile stretch of Yorkshire coastline. Starting at the highest point along this coast, Kate heads down into the fishing village of Staithes, which was once home to one of north Yorkshire's largest fishing fleets. In Runswick Bay, she takes to the sea with the volunteers in the newest rescue boat. Kate then heads on to Whitby, which inspired Bram Stoker's Dracula after he stayed there in 1890.

The naturalist walks 12 miles of Suffolk's shingle coast, starting at Minsmere Nature Reserve, and later heads through the protected wetlands at Snape Maltings in a kayak. Her final destination is the 10-mile-long shingle spit at Orford Ness, a former military test site which is now a National Trust nature reserve.
