Abu Dhabi is the capital and the second most populous city of the United Arab Emirates, and also capital of the Emirate of Abu Dhabi, the largest of the UAE's seven emirates. Abu Dhabi’s rapid development and urbanisation coupled with the relatively high average income of its population has transformed it into a large but open metropolis. It is a popular base for many international organisations which has in turn created an extremely diverse culture that makes for a fascinating experience. The often slick and modern capital of the U.A.E. presents a fascinating mixture of tradition and progression. Tracing its rich history back to around 3000 B.C., Abu Dhabi maintains a more distinctly Arabian ambiance than glitzy Dubai. Taxis are a safe, reliable way to get around the city, as well as bus services throughout the region.
