Topping our ranking of Spain's best hidden gems is the smallest, sleepiest and least well-known island in the Balearic archipelago. Formentera is an unspoilt paradise just 30 minutes from Ibiza by fast ferry. Discerning travellers don’t come to Formentera instead of its more famous sisters – they come here on its own unique merits.

The vibe is cool and calm, where slow living is not only encouraged, but unavoidable. Fig trees, pine forests and salt flats scatter the laid-back island, giving way to incredibly serene beaches like Ses Illetes (pictured). Buzzy Es Pujols is the go-to spot for restaurants and nightlife, while the Dunas de Formentera hotel is the epitome of barefoot luxury.
