Jules Hudson explores the waters of Hampstead Heath which have been used for over 200 years by champion swimmers and year round bathers. How and why did they come to be and what stories can they tell? How has the landscape around them changes and what is it about them that still draws over a quarter of a million visitors a year? And what does the future hold for them? Jules Hudson is joined by Caitlin Davies who has swum in the ponds all her life to find out more about these unique ponds.
