There are people here that you can hire to drive you wherever you would like to go. Ladies can not drive around Saudi Arabia. They either have to take a bus, taxi, or hire a driver. If you are with Aramco, you can check at the AAA garage, or at the CCC office to enquire about hiring a driver.
Aramco offers free bus service for their employees and their famililes. They are nice busses that are air conditioned and will take you all around the community, as well as into Al Khobar, or to the other Aramco Communities. Just grab a bus schedule, hop on the bus, and it will take you to your destination. Sometimes you need to change busses, but it is a way to get around.
