Ten million people call vibrant, passionate, sprawling Bogota home. A city of startling contrasts, with affluent areas, slums and everything in between, it's best discovered on foot - with a trustworthy guide. La Candelaria is a historic walking neighbourhood. North Side offers upmarket shopping. Attractions aren't thin on the ground, although air is: the city sits at an altitude of 8660 feet. Cathedral de Sal, Museo de Arte Colonial and Museo de Oro are rich reminders of Columbia's history.
