Five days is enough for Carthage, El Jem, Kairouan and the Sahara — but only if two of those days are spent moving south. The workable shape is one day around Tunis, then a three- or four-day circuit into the desert and back, rather than trying to base yourself on the coast and make day trips. Tunis to Douz alone is about 426 km each way.
Enough for the highlights of the north and a proper look at the Sahara, yes. Not enough for Djerba, Tabarka and the far south as well.
Not if you want the desert. The distances make a single base impractical; the south needs at least one overnight closer to it.
October to April if the itinerary includes the Sahara. The deep south regularly passes 45°C between May and September.
Distances are straight-line, measured between the coordinates on our map of the sites; road distances are longer. Prices are per vehicle and come from the same database the 28 tours and 1,392 transfer fares are quoted from.
