Britain's Best Walks with Julia Bradbury 1x5

In East Sussex, the expert walker sets off from the village of East Dean, as she explores one of the longest undeveloped coastlines on the south coast - one that is disappearing at an erosion rate of almost one meter a year. During her three-hour walk Julia discovers the area's rich social history at seaside settlement Birling Gap, learns of the mystery of Sherlock Holmes' retirement, and hears how a lighthouse had to be shifted 17 metres back from the cliff edge.
