For adventurous souls only, Cartagena's labyrinthine central market is both dirty and enthralling, an all-out assault on your senses. If it's marketable, it's for sale here: there are endless stalls of fruits and vegetables, meat and fish, and plenty of options to grab a quick bite or juice up on a chilled beverage. Don't wear flashy jewelry and pay close attention to your belongings. Grab a taxi (COP$7000 from the Old Town) and explore away.
