The tourist office in Plaza de la Aduana is a recommended first stop before you embark on any sightseeing in Cartagena. Here, you can view a map of the whole city where sites light up based on the activities that interest you. Store up on tourist magazines and maps for free.
Banks are located along Avenida Venezuela.

Internet is readily available throughout the city for about 1.500 pesos per hour, and is particularly easy to find around Calle Santo Domingo in El Centro.
Because there is a lack of space for lavanderías to wash your clothes, it’s best to ask your hotel for their services.
Finally, if you are in need of a doctor, the best are found outside the walled city at the hospital in Bocagrande or Ami in Pie de la Popa.
