In Copenhagen harbour

In Copenhagen, you are always reminded you are very close to the water, even if it is only thanks to the sounds of the seagulls.
To visit the harbour, nothing easier! You just have to jump on a yellow bus boat (run all year long, even in the frozen winter). A boat line is going from the north (close to the Little Mermaid) to the south (close to the library). Most transportations passes (like a valid 10 rides card) are accepted!
Just imagine that some people use those everyday to go to work!
