Heading to Italy this summer? See the Amalfi Coast, then head to Puglia. Puglia, an Adriatic Sea town in the heel of Italy’s boot, is quieter and less frequented by tourists than the Amalfi Coast. In addition to sunbathing on gorgeous beaches, see the historic architecture of Castel del Monte and the trulli of Alberobello, both recognized as UNESCO World Heritage Sites. Make sure to book a table at Grotta Palazzese to dine inside a carved-out limestone cave with a view of the sea.
