The trip to Colombia - Cartagena -Getting there

Definitelly Cartagena is the main atraction Colombia has to offer, you could even skip Bogota for that matter. Cartgena is one of the prettiest cities in the Ameicas matching Quebec city (Canada), puebla (Mexico) and Fortaleza (Brazil).

In my case I went from Bogota via twingo low cost airline for 50 bucks round trip.
The Rafael Nuñez Aiport is very close to the Old city, you could even walk, but do grab a a cab specially if it hot.
Do not take a cab a at the Airport, actually never do that anywhere, just ask and walk one block to the "Calle 70" and there look for the tiny Hyundai cabs, not anything bigger. Those cabs are shared and they pick up people as they go, they will honk at you or u can do the peace sign, that actually means two for $2000 pesos that is the going fare.

And thus avoiding being overcharged on arrival.
