Tiny islet Spinalonga is just a short boat trip away from northern Crete, but a visit is like stepping back in time. Centuries of history are packed within the walls that encircle this islet, which is no more than 435m long and 230m wide. Over the centuries, Spinalonga has served a Venetian fortress, an Ottoman town and a leper colony, which closed in the 1950s and led to it being known as the ‘Isle of Tears’. You can wander around its eerily empty streets, past roofless, doorless and windowless houses whose walls have so many tales to tell. Take a look round the old hospital and graveyard, then amble up to the ruins of the Venetian castle for panoramic views over the islet, Plaka and Kolokitha peninsula. Another great way to explore this island is with a guided tour.
