Interesting port to visit. Lots of old world there. Stroll through old town flowered balconied streets and visit the Inquistion area and see torture devices. Colombia can be dangerous, but in a group here ok.
A well developed tourist spot over the years, it is losing some of it's charm. Typical Senor Frogs type establishments. Spend your time in the market area on your own over a tour. Typical chinese made Mexican nick-nacks, tee shirts, straw
