In this program, Zay Harding embarks on a five day voyage from Cape Town on the last authentic British Royal Mail Ship, travelling 2000 miles across the South Atlantic to one of the world’s most remote inhabited islands – the tiny British Overseas Territory of St Helena, marooned over 1300 miles from the nearest mainland. The island is blessed with spectacular scenery and a fascinating history, but as yet it has no airport, so it’s very rarely visited.
