1. Walk along Charles Bridge
The most famous and most crowded spot to be. The view over Moldau, up to Prague Castle is beautiful. I`d recommend the evening hours, the light is so nice during sundown. Take your time, listen to street musicians and simply enjoy the atmosphere. There are two or more statues that you should touch, because it brings you luck or may even make a wish come true. You can easily recognize them, the have shiny golden parts.
