Tunisia has a number of international airports to service its sizable tourist trade. Tunis is the center of the transportation system as the largest city having the largest port and a light transit system. Most Tunisian taxis are known as louages, long-distance shared vehicles similar to minibuses. Louages travel throughout Tunisia but do not depart until there are a sufficient number of passengers inside. Louage fees are roughly on a par with Tunisian rail and bus fees, and stations are situated throughout the country. Western-style private taxis are most easily found in Tunisia’s largest cities and resorts. Inter-city bus service in Tunisia is fairly easy to use and vehicles are comfortable. Many Tunisian long-distance buses are known as ‘car,’ and buses labeled ‘car comfort’ contain air conditioning and television. ‘Car’ buses travel between Tunis and Hammamet once every half-hour, and departures at most other Tunisian ‘car’ bus stations are equally frequent.
