Al Khobar is located in the eastern province of Saudi Arabia and lies 400km away from Riyadh and only 120km to Al Jubail industrial city. Many modern roads link all cities in Saudi Arabia and other GCC countries. In addition, there are 3 major airports in Riyadh, Jeddah and Dhahran which shorten the travel time between the cities.
Al Khobar can be reached by plane through domestic or international flights. If you are coming from Riyadh you may use the train. Car rental companies are widely available in addition to local white taxis - just make sure you agree on the fee before you depart.
The Immigration Authority of the Kingdom of Saudi Arabia rules that entry visas are required for all nationals with the exception of the GCC. Please contact the nearest embassy to obtain your personal visa.
