At 8km long, Gan – not to be confused with the other two Gans in the south – is the longest island in the country and one of the most interesting too, boasting a large (by local standards) lake and a slew of Buddhist ruins. As Gan is connected to Kadhoo and Fonadhoo by causeways, it’s possible to explore other nearby islands without hiring a boat, making this a great choice if you’d like to see lots of local life.
