The national train company SNCFT (http://www.sncft.com.tn) 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 12/10/6 dinars 6/5/3 Euros 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 20 dinars 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 1,50 dinars 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 railway Called TGM also connects Tunis northward to Carthage and Marsa. Take this light railway system to Sidi Bou Said as well. One-way light railway tickets will cost approximately 675 millimes 1 Dinar = 1,000 millimes.
SevenAir 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 Bizerte. French-only website, booking still not online only through agencies SevenAir (http://www.sevenair.com.tn).
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 â¬40 for Tunis-Hammamet or â¬50 for Monastir-Hammamet (http://www.taxitunisie.com).
Long distance bus called car (http://www.sntri.com.tn/) 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.
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. They are nearly as cheap as the walk up train fares and operate with fixed prices so you won't get scalped. eg 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 and tourists may be hassled. 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. 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.
