When it comes to the more far-flung parts of the world, they don’t come much more remote than the island of St Helena in the South Atlantic.

Not only is it not on the map for any of the mainstream cruise lines, it receives only a handful of ship visits each year. Which is pretty significant when you discover this distant outpost – a British Overseas Territory 1,500 miles north-west of Cape Town in South Africa – can ONLY be accessed by sea.
