Tourism accounts for 18% of Greece’s GDP, directly or indirectly employs more than 900.000 people, and is the leading source of the country’s invisible receipts (36% in 2007). 

Currently, more than 9,000 hotels operate in Greece. Due to Greece’s many islands and islets, more than 6,000, the geographical range of tourism destinations is extensive. In addition, the wide variety of natural landscapes, extensive number of historic sites and villages, and wide-ranging number of activities mean that opportunities are virtually limitless. 

Approximately 85% of arrivals originate in Western Europe: 21.2% from the United Kingdom, 17.5% from Germany, 8.8% from Italy, 5.3% from France, 5.2% from Holland, and 7.5% from the Scandinavian countries. 

Increasingly, however, significant numbers of visitors from Eastern Europe and China are making Greece their preferred destination, creating a wider base of origin countries and new demands for services, facilities, and attractions. (Enterprise Greece)
