We spent almost 3 weeks in Colombia in December, 2015. We traveled to Bogotá, Medellin, San Andres, and Cartagena (where most of these images were taken).
One of the highlights was the grafitti tour in Bogota, where we learned the history of the artists who created them, and their politics.
Of the cities, Cartagena was our favorite. If not for the oppressive heat and humidity (90 and 90...), we would have loved to stay longer.
