Cala Macarelleta has to be seen to be believed: an arc of icy white sand lapped by gentle waves of unearthly blue. Incredible beaches like this are just one reason Ibiza graduates are increasingly flocking to Menorca, the most nonchalant of Spain’s dazzling Balearics. On this low-key island there are more Neolithic monuments than trendy beach clubs and some of the loveliest hotels are rustic stone villas strewn with purple bougainvillaea. Even at the height of summer, you could stumble across one of Menorca’s best beaches and find it completely empty except for a few dozing cows. This is the Mediterranean in its purest form.
