Tunis (تونس) is the capital of Tunisia.
Located on the Mediterranean coast but lacking much in the way of beaches, Tunis has been spared the onslaught of package tourism in the resorts to the north and south. There isn't much in the way of must-see attractions, but Carthage is easily accessed from here and the souq is one of the most authentic and hassle-free in North Africa.
Tunis-Carthage Airport (TUN), 8 km away from the center, is small and in reasonable shape with all standard facilities. You can exchange money here at decent rates. A taxi into the city center — insist on the meter — shouldn't cost much more than 5 dinars. Alternatively, you can hop on the nearby TGM train line to the center.
Tunis Central Station is near Place de Barcelone for easy interchange onto the light metro.
Tunis is well-served by a convenient four-line light metro system run by Société des Transports des Tunis  (French/Arabic only). The interchange hub for all lines is in the center of town at Place de la République/Place de Barcelone. Single trips cost 0,410 TD.
The TGM suburban train line, starting at Tunis Marine station on Lines 1-4, connects to La Goulette (ferries), the airport, Sidi Bou Saïd, Carthage and the beaches of Marsa.
