Large green-and-red-signed Metrocar buses shuttle between the city and the bus terminal every 15 to 30 minutes (COP$3000, 40 minutes). In the center you can catch them on Av Santander. A taxi from the bus station to El Centro costs COP$15,000, plus COP$5000 after 8pm.
In 2016 Cartagena inaugurated BRT Transcaribe, a rapid-transit system similar to Bogotá's Transmilenio, with buses operating in special busways. Further development is expected, but for the time being the network's single line is tailored more to locals than visitors.
