Most people land in Tunis, look at the map and head straight for a beach resort. That's a mistake of about five days. This is a capital with a medina holding some 700 monuments (UNESCO since 1979), a French-built avenue ten minutes away on foot, and, 17 km up the coast, the Phoenician city of Carthage, which Rome destroyed in 146 BC and then rebuilt a century later as its own. Its columns ended up in the medina's great mosque. You can follow that thread with a ticket that costs less than lunch in Europe.
Tunis isn't polished. The medina is a working market with touts at the edges, the avenue has seen better decades, and the biggest mosques are closed to non-Muslims. In return you get a city that hasn't been rebuilt for tourists. The Bardo has one of the largest collections of Roman mosaics in the world, the light rail takes you from downtown to a Roman bath complex by the sea, and Sidi Bou Said, the blue-and-white hill village, was added to the UNESCO list in July 2026, Tunisia's tenth site. Five days is the right length: three would force you to choose between Carthage and the medina, and ten would start to repeat itself.
The plan keeps each day in one place. Day one is the medina and its souks, day two the Bardo and the French-built new town, day three Carthage, day four Sidi Bou Said and the northern coast around La Marsa, and day five a day trip to Dougga, the best-preserved Roman small town in North Africa. Start on a Tuesday: the Bardo and the medina's house museums close on Mondays, and the Friday slot then falls on the coast, away from the medina's busiest prayer day. November is mild but changeable (see below), so each day has an indoor fallback. If you want more of the country, Tunisia has the full picture, and the last section here lists the day trips that didn't fit.
