Greece is known for its natural beauty and fascinating history. Ancient archaeological sites, countless islands, sandy beaches, and a balmy Mediterranean climate make Greece one of Europe's prime tourist destinations. Besides the capital, Athens, top things to see on the mainland include Ancient Delphi and the monasteries of Meteora. But most people come here to catch a ferry to the islands; Santorini, Mykonos, Rhodes, Corfu, and Crete are the most popular.
