Charlotte Church rose to global fame at just eleven years old, renowned for the extraordinary purity of her singing voice. From growing up in what she describes as a working-class household in Cardiff, her career took her to the world’s grandest stages, performing for audiences which included the Pope and the U.S. President, and releasing best-selling albums. But that early fame also came with its own set of challenges, some of which, she explains, she is still "not quite grateful for, yet... but what teaching!"

Today, Charlotte’s preferred concert hall is something entirely different: the vast and spectacular landscape of the Cambrian Mountains in mid-Wales. Here, she has established a rural retreat. Tucked away in the Nant Caethon Valley and framed by two waterfalls, it’s a place of healing – for herself and for those she welcomes.

Charlotte serves as a guide to Martha Kearney, sharing why this place holds such deep meaning for her. She speaks about her efforts to restore and protect the Celtic rainforest she now calls herself a guardian of. Together, they reflect on Charlotte’s journey – from a child star with little connection to nature, to someone now deeply immersed in the natural world.

Author of The Salt Path Raynor Winn takes Martha Kearney back to walk part of it: the south west coast path from Polruan in Cornwall, where her story ended and where the new film of her book is set. She talks about what nature means to her and how it effectively saved her life, and that of her husband, Moth. They set out to walk the 630 mile coast path when they lost their home and livelihood, and Moth was diagnosed with a terminal illness. They walked through it all and came out at the other end with renewed hope.

Raynor Winn is a long-distance walker and writer whose first book, The Salt Path, was a bestseller. Since then she's published The Wild Silence and Landlines, which also ends in Polruan, where she lived for some time. She grew up on a farm in Staffordshire and has always lived in the countryside. She tells Martha Kearney about her isolated rural childhood and how she feels most at home in nature. Her experience of homelessness changed her view of what home is. On a surprisingly blue and sunny but blustery day they walk the path as she and her husband did and Raynor recalls that time and reflects on how that experience has changed her.
