There is a way to experience Orpington in a unique manner by visiting the tunnels of Chislehurst Caves, you’d realize that it used to be a mine for chalk and flint in the past. Another place to visit is Charles Darwin Down House residence; the Priory Gardens which is a kid-friendly park; the Canadian Corner War Graves, a burial spot of Canadian soldiers who died during the First World War in Orpington’s hospital.
