The zem (zemidjan) is the defining way to get around Cotonou. These motorcycle taxis are everywhere — estimates put the number at over 100,000 operating in the city — and they are fast, cheap, and the only realistic way to cut through the traffic. Negotiate the price before you get on; short trips across town should cost very little. Wear a helmet if one is offered.
Shared minibuses (called SOTRA or simply car gare) run fixed routes and are cheaper than zems but slower and more confusing for visitors. Metered taxis exist but are rare; Cotonou has some ride-hailing apps, though penetration is limited compared to Lagos or Accra. Walking is fine in the central commercial districts during the day. At night, stick to well-lit main roads.
The city has grown organically and street addresses are unreliable; locals navigate by landmark. The Dantokpa market, the Ancien Pont, the BCEAO Tower, and the Jonquet roundabout are the main reference points in the centre.
