Up until the 1970s, postmen and women in rural areas walked their delivery rounds - taking routes through the hills dubbed "postal paths". Some routes, and fragments of others, still survive today. In this programme Helen Mark explores one of them, near the village of Shap in Cumbria, with author Alan Cleaver who is writing a book about these old paths. So far he's identified over thirty of them up and down the UK. Others have now been built over and are gone forever. Alan tells Helen about the cultural significance of the postal service in the past, recounting the poignant story of a man who used to write letters to himself, just so that the postman would call by and he would have a visitor. Alan and Helen discuss the disappearing role of postmen and women, in the age of electronic communication.
Helen also explores part of Shap's old Corpse Road, which linked Swindale Head with Mardale - a village which didn't have its own cemetery until the mid 18th century. Before that, bodies had to be carried over the fells to Shap for burial - a distance of about eight miles. The last body was carried along the Corpse Road in 1736. Local historian Jean Scott-Smith tells the story of the Corpse Road and shows Helen part of the route.

The Broomway has been dubbed the “deadliest footpath in Britain”, claiming more than a hundred lives. Helen Mark takes a cautious walk along this treacherous Essex seapath with Peter Carr and John Burroughs from the Foulness Island Heritage Centre. She’ll hear how people can easily become disoriented on the vast mud flats and tragically caught out by the rapidly advancing tides of the Thames Estuary. Helen will also be joined by Thea Behrman, the director of the Estuary Festival, to reflect on how this meeting point of land and sea can provide creative inspiration through its bleak beauty.

Over the centuries the River Quoile has carried Vikings, steam ships and cargoes of coal and timber from as far afield as the Baltic and Canada. Today it's a river for leisure pursuits – popular with canoeists, anglers and wildlife enthusiasts.
Cadogan Enright is a councillor, environmental campaigner and chairman of the local canoe club. He takes Helen Mark out on the river to sing its praises, but also to point out concerns. He tells her that Downpatrick and the surrounding countryside were prone to tidal flooding in the past, but now the threat comes from the land - with increasing winter storms leaving the land saturated. Helen meets Robert Gardiner, chairman of the railway museum, who shows her how the water flooded their exhibition gallery last year and has threatened the museum's financial future.
Back on the riverbank, Helen meets Stephen O'Hare, a member of the River Quoile Trust which campaigns for improvements to the river. He shows her the remains of quays along the riverbank, which were once busy dockside areas for cross channel steam ships during the industrial revolution. Trade died out because of the unpredictability of the tides and the difficulties of navigating Strangford Lough out to the Irish sea, and came to a halt in 1957 when a flood barrier was built at the mouth of the river.
As for the Vikings – they haven't quite disappeared. Viking historian Philip Campbell and a group of enthusiasts have built a re-enactment village and a replica longship which they sail on stretches of the Quoile. He tells Helen that, as its dragon head noses through the waters which wind around the gentle drumlin countryside, he is filled with appreciation for the beauty of the river and its importance through the centuries.

Bernard Bishop has lived and worked on the Cley marshes for his whole life. It's the Norfolk Wildlife Trust's oldest reserve and home to a plethora of birdlife, sealife and grazing saltmarsh cattle. Bernard and his family have been cutting reeds to be used for thatching from the marsh for five generations and counting. Bernard talks to Ruth Sanderson as he cuts this year's reed crop with his son and nephew. With birds calling overhead, he reflects on a life spent working in and loving this very special landscape.

For over two decades presenter and wildlife expert Philippa Forrester has lived in a house with a river flowing through the garden. It's home to an abundance of species including Kingfisher, Mink and Egrets, and it's been the backdrop to a remarkable period of time when Philippa helped raise two orphaned otter cubs ready to be released back into the wild.
In this programme Philippa tells some of the stories of this river, and remembers how whole trees and even a car have come floating past after particularly heavy rains. She talks about how the river changes in the seasons, but also how she's seen legions of Signal Crayfish marching down after the sluice gate has been opened. Philippa drops down to Keynsham to speak to Simon Hunter about what can be done to help tackle this invasive species, and Ben Potterton from The Otter Trust pops over to the house to talk about those enigmatic and elusive carnivores.
