General info

Jordan is in the "red" zone of Middle East adjacent to Syria from the north, Iraq and Saudi Arabia from the east and Israel and West Bank from west. In this land leave more than 3,24 million Palestinians. Most of its inhabitants are Muslims and speak Arabic while country's currency is dinar (JOD). Amman is the capital, deemed to be one of the world's most archaic cities as many archaeological findings point to the existence of settlements dated from the 13th century B.C. Jordan has the 2nd smallest coastline in the world, only 41km from which almost the 18km were incorporated in 1965 after exchange of land with Saudi Arab. It also holds the 2nd position in the list of countries with poor water supplies. 

At a great extent people occupy with livestock as it is not yet industrially developed enough. Tourism on the other hand is a substantial source of income, even though it was hammered by Middle East's turmoil during the last years. However, Jordan still remains a safe country

Visa is a prerequisite to enter the country. Yet, if you arrive in Aqaba and leave from there too there is no need for a visa. Jordan is 2:30 hours far away from Greece. If you are planning to visit a lot of sights you may obtain a Jordan Pass that offers you free entrance in many sights, Petra included. It also provides you a visa in case of not entering the country from Aqaba. (https://www.jordanpass.jo/)
