In the first of the series Clare joins keen walker and Director General of the National Trust, Dame Fiona Reynolds, to walk a section of the new Octavia Hill Centenary Trail in Kent. Co-founder of the National Trust, Octavia Hill passionately believed that green space was essential for a healthy lifestyle and spent her life campaigning to save these disappearing open spaces from development.

Beginning at Toys Hill in Kent, one of the places that Octavia managed to save, Clare and Fiona set off to walk part of the Trail which has been created to mark the centenary of Octavia's death. A keen walker herself, Fiona tells Clare why she finds Octavia Hill's legacy so inspirational and why walking and the British landscape is so important to her.
