One of Denmark’s cheapest and most colorful vacations is a few hours riding back and forth on Copenhagen’s big yellow Harbor Bus, or “Havnebussen”, a commuter ferry designed to transport ordinary citizens between downtown and the urban islands of Christianshavn and Amager. For visitors to Copenhagen - or residents who need an inexpensive adventure -  the harbor bus can take you from tourist trap to high culture to party culture, from shabby little wood shacks to neighborhoods of chic glass apartment houses with their own private beach. All for as little as 14 kroner, 2 dollars, or 2 euro. Enjoy this audio tour of 7 of the "Harbor Bus" stops - if you like, you can take it along and listen as you ride the waves.
