The busiest and biggest island of Turks and Caicos, Grand Turk is a likely port if you’re cruising around the balmy region thanks to a state-of-the-art cruise hub. As well as a fairly impressive historical centre – the island is thought to be Christopher Columbus’s first stop – it’s also a hub for keen divers thanks to a coral reef easily accessible from the beach and a regular crew of humpback whales that migrate past each year.
