Sprinkling the Mediterranean, the Balearic Islands—50 miles and an eight-and-a-half-hour sail from Spain's eastern coast—offer limpid waters, well equipped ports, and an infinite number of of small calas, or coves, into which you can put in and be alone. For restaurants and throbbing nightlife, put in at Ibiza or stylish Palma de Mallorca. For quieter moorings, point the prow to Minorca, easternmost of the islands and its quaint capital of Mahon, or to the intimate harbors of Addaya and Fornells. For true tranquillity, drop anchor near the nature preserve on Cabrera Island (you'll need a permit), Sa Dragonera, or the uninhabited islets of Espalmador and Espardell.
