Moving around Qatar is quite easy and there are several options available to visitors. Limousine services are available through a variety of companies. More expensive than taxis, but very reasonably priced, late model vehicles with knowledgeable drivers are provided. The most economical method is the white and orange taxis. Although there is no central dispatch to call a taxi, you can easily wave one down. Another option is renting a vehicle from one of the many operators located in Qatar.
