Tunisair express is the domestic airline branched off of TunisAir. You can fly between Tunis and Tozeur, Djerba and Gabes, as well as flights to Malta and Napoli. French-only website, booking is available online or through agencies Tunisair Express.
Tunisian highways resembles US Interstate or the highways of Europe with a dual carriageway: A-1 runs from Tunis south heading to Sfax, A-4 runs from Tunis north heading to Bizerte, and A-3 runs from Tunis West heading to Oued Zarga. Tunisian highways speed limit is 110 km/h. It is possible to maintain that speed on that road very easily. The routes shown on some maps have a planned extension to Gabes then Ras Jedir (Libya Frontiers) in the South as of 2011-2014 and to Ghardimaou (Algerian Frontiers) in the West, but several years later. The remaining highways have single carriageways, with traffic round-abouts at major intersections, which follow the European model (those in the roundabout have the right of way). Consequently, on roads other than the A-1,4,3 it can be difficult to maintain an average speed of more than 75 km/h most of the time as the speed limit is 90 km/h. Almost all road signs are in Arabic and French.
Like most developing countries, road accidents are the leading cause of death and injury in Tunisia. Tunisians are aggressive, poorly skilled and discourteous drivers. They are unpredictable in their driving habits, jumping traffic lights, seldom signaling when changing lanes, often ignoring traffic lights and stop signs, driving at very high rates of speed regardless of the quality of the roads or condition of their vehicles, and stopping at almost any location even though it may block other cars or potentially cause an accident. Because of the lack of sidewalks, pedestrians walk on the roads often without regard for cars or their own safety. Sadly, Tunisians seldom secure their children in appropriate car seats and these tiny passengers often bear the brunt of most accidents.
Although police are visible at many major intersections, they seldom enforce traffic rules or stop bad drivers unless it is to solicit bribes.
People unfamiliar with driving in developing countries are best to use public transportation or hire a driver.
Driving in Tunis is further compounded by narrow streets and limited parking spots. To see the Medina of Tunis, it would be best to park some distance from the Medina, and take the light rail (called TGM) in from Marsa/Carthage, the green tramway (called Metro) downtown, or perhaps a taxi in from the nearer outskirts.
Rental cars are fairly easy to find, but somewhat expensive, at DT100 or so a day, for a medium sized car such as a four door Renault Clio.
Private taxis are reasonably priced even for long-distance travel, just be sure to agree on the fare before you set off. Sample fares for a four-seater are €40 for Tunis-Hammamet or €50 for Monastir-Hammamet. When taking the taxi within bigger towns such as Tunis, there are meters installed. Make sure it is started when you leave and in the corresponding mode (night, day, etc). A green light indicates that the taxi is already taken, a red that it is free.
The national train company SNCFT runs modern and comfortable trains from Tunis south to Sousse, Sfax and Monastir. There are three classes of service, namely Grand confort (deluxe 1st), 1st and 2nd, and all are quite adequate. Example fares from Tunis to Sousse are DT12/10/6 (€6/5/3) in Grand/1st/2nd class. Although tickets are issued with wagon/seat numbers marked on it, that is largely ignored by locals. So if you are travelling with more people, try to get onboard quickly to find adjacent seats.
A good thing to do is to buy a carte bleue (blue card). It costs around DT20 for a week and you can travel all around the country using the banlieue (short distance train) and grande ligne (long distance). For the long distance you will have to make a reservation and pay a small fee (DT1,50 or so). These passes can also be bought to cover 10 or 14 days. There are rarely queues at the booking office and a little bit of French goes a long way. Trains go also to Tozeur and Gabes in the south where it is easy to access the Sahara and Ksour regions respectively. In some stations where the frequency of trains is small (e.g. Tozeur), the ticket booth will remain closed for most of the day and reopen around the time of the departure of the next train.
A light railway (called TGM) also connects Tunis northward to Carthage and La Marsa. Take this light railway system to Sidi Bou Said as well. One-way light railway tickets will cost approximately DT0.675.
Locals use louage or long-haul shared taxis where there is no train or bus. There are no timetables, but they wait in the louage station (which is generally near a train station if your destination is accessible by train) until 8 people turn up. The wait is never too long in major cities, most of the time less than half an hour. They are nearly as cheap as the walk up train fares and operate with fixed prices so you won’t get scalped. e.g. Douz to Gabes (120km) for 7 dinars. Be aware that while louages are very cheap, they can also be stifling hot during the summer months (although the windows are left open during the ride and that helps!) and tourists may be hassled, if only rarely – most locals will keep to themselves. Furthermore, louages have the reputation to drive at a fast pace, and to be less safe than other transportation, so be aware of that. Louage departures are very frequent, a louage departs as soon as the seats are filled. It is acceptable to pay for an empty seat to leave earlier. All Louage cars are of white color, with a side stripe showing the coverage area. Louages between major cities are recognizable by their red stripe, louages within region are recognizable by their blue stripe and Louages serving rural areas are recognizable by their Yellow strips (the Rural Louage can be Yellow with blue stripes, or a van fully painted in brown color).
Long distance bus (called car) is also a safe and economic way to travel between major cities such as Tunis, Nabeul, Hammamet, etc. You will generally find a station in each major city offering many departures per day (every 30 minutes between Tunis and Hammamet). Some of the bus locally called “car comfort” offer higher standards (TV, air conditioner) at cheap prices. Hours can be found online.
