The TGM is the little light-rail line that runs from Tunis Marine across the lagoon causeway and along the coast to La Marsa, and it is the simplest way to see the sea suburbs without a car. A self-guided day on the line costs little, lets you move at your own speed and puts three of the best stops in the country within a few kilometres of each other. This guide explains how to plan it, where to get off and how to avoid the usual mistakes.
How the line works
Trains leave Tunis Marine frequently, and the journey to La Marsa takes about half an hour end to end. The stations that matter are Carthage Salammbo, Carthage Hannibal, Carthage Byrsa, Carthage Dermech, Sidi Bou Said and La Marsa. Buy a ticket at the window before you board, keep small notes handy and check the first and last services, because late trains can be sparse. The line is busy at commuting hours, so late morning is more comfortable. Platforms are low, so watch your step when boarding with a bag or a stroller.
Start at Carthage Hannibal
Begin in the south with the Antonine Baths, a short walk from Carthage Hannibal. The ruins sit on the shore and take about an hour, with underground corridors to explore and a tall reconstructed column that gives a sense of scale. Early morning is best, before the sun is high and the coach tours arrive. Wear sturdy shoes, because the paths are gravelly and some steps are uneven. Carry water, as shade is limited on the upper platform.
Walk on to the other Carthage sites
The Carthage ruins are scattered across several neighbourhoods rather than gathered in one park, so allow time to walk between them or take a short taxi. The theatre, the Roman villas, the Punic ports and the Tophet each have their own entrance, and some sell a combined ticket. Byrsa Hill gives the best overview of the ancient city and the gulf beyond, and the museum building there has been awaiting renovation, so plan around the open-air sites. If you want help reading the stones, a guided bike tour or a half-day guided walk makes the scattered layout much clearer than a map does.
Lunch in Carthage or on the way
Carthage Dermech and the streets near the station have simple cafes selling brik, grilled fish and fresh juice at modest prices. If you would rather wait for Sidi Bou Said, take a pastry and water for the walk and eat on the clifftop. Keep lunch light, because the afternoon involves climbing.
Continue to Sidi Bou Said
From Carthage Dermech or Byrsa, ride one or two stops to Sidi Bou Said station. The village is a steep uphill walk from the platform along a cobbled road, so wear comfortable shoes. Once at the top you find whitewashed houses, blue doors and shutters, jasmine in the lanes and a view over the harbour. Visit the main square, wander the alleys, and look for the old cafe on the terrace where mint tea with pine nuts comes with a view. Mid-afternoon is busy; the late-afternoon light is soft and the crowds begin to thin.
Finish in La Marsa
If you still have energy, ride one more stop to La Marsa, a lively beach suburb with promenade cafes, ice cream stalls and a wide sandy beach. It is a good place to watch the sunset and to rest your feet before the ride back. Taxis wait near the station if you prefer not to take the train after dark.
Practical tips
Dress modestly outside the beach area, and carry a scarf or light cover for religious sites. Keep valuables in a zipped bag on crowded trains, and agree taxi prices or insist on the meter. In summer start very early, because the middle of the day is hot. In winter some cafes close early, and rain can make the Sidi Bou Said cobbles slippery. Take a small amount of cash for tickets and snacks, since not every small business takes cards.
Choosing between self-guided and a tour
The self-guided route suits independent travellers who like to wander and have a full day. A guided half-day tour takes the logistics away and helps with the history, which can be valuable at the scattered Carthage sites. Many visitors do a guided morning and then spend the afternoon on their own in Sidi Bou Said. Whichever you choose, aim to arrive at Sidi Bou Said for the last couple of hours of daylight, when the white walls turn warm and the harbour fills with boats.
