Every visitor is aware of the existence of Amsterdam's red light district, locally referred to as De Wallen. Some head there straightaway while others prefer to walk around it — the choice is yours. The truth is, you will likely end up wandering through the area simply because of its location right in the city centre. The best way to get acquainted with the city's most notorious neighbourhood and discover its stories and secrets is by joining a walking tour. Follow your guide through winding cobblestone streets and narrow alleys as you learn the history behind Amsterdam's infamous adult destination. See, along the way, oddities like the world's first condom shop, the Museum of Prostitution, as well as little-known sculptures, and sex theatres.
