Why Tunis for a city break?
Tunis is the most underrated North African city break available to UK travellers — a city of 2.7 million people where the medieval medina (a UNESCO World Heritage Site of extraordinary completeness) functions as a fully alive urban neighbourhood rather than a tourist attraction, where the ruins of Carthage are 20 minutes from the city centre, and where the Bardo National Museum holds the world's finest collection of Roman mosaics. It is genuinely and significantly cheaper than Marrakech, less touristy, and rewards visitors with a depth of North African culture and history that the more heavily marketed Moroccan cities sometimes obscure.
From London and several UK regional airports it's around two hours forty-five minutes — direct Tunisair and Transavia flights make it one of the most accessible North African destinations from the UK. Tunis-Carthage International Airport is 8km from the centre (taxi, around 20 TND, under £5). Go in spring (March to May) or autumn (September to November): the Mediterranean climate is perfect, the medina is comfortable to walk, and the Roman sites are at their finest. Summer can be very hot but the beach resorts of Hammamet and Sousse are 60-90 minutes south if sea and sand are the priority.
