A new stretch of Copenhagen's speedy, "driverless" Metro service has just opened, connecting Copenhagen Airport with the city center.
The trains travel along the eastern shore of the island of Amager then west into the city and beyond to the Frederiksberg and Vanløse neighborhoods. Although the modern trains are driverless, there is a Metro Steward aboard to ensure everybody's safety.
The trip from the airport to Kongens Nytorv in the city center takes just 15 minutes and costs just $4 - or, it is free with a Copenhagen Card.
After you finish travelling green, you can eat green, too, since eating organic in Copenhagen is incredibly easy with organic produce, meat, milk, cheese and other products widely available at supermarkets and restaurants.
Danes have long been world leaders in organic food production; in Denmark eco-conscious eating is simply a way of life!
Top organic spots in Copenhagen include the casual café BioM - where even the paint on the walls is eco-friendly - and Gourmandiet, both in the Østerbro section of town, as well as Cap Horn (arguably Copenhagen's first organic restaurant) located prominently on Nyhavn, the historic canal district.
