MONTENEGRO // The impossibly picturesque walled island village of Sveti Stefan guarantees the greatest 'wow' moment along Montenegro's Adriatic coast. Terracotta-roofed graceful stone villas and clusters of pine and oleander overlook a gorgeous pink-sand beach lapped by turquoise waters. Now converted into a luxury resort and off limits to non-guests, the island is linked to the mainland by a narrow causeway and can be visited on exclusive guided tours.
