I recommend to all those who want to walk and spend their time really getting to know Prague to take the Prague Card. With a card they can see many attractions and have many discounts and for someone like me who has taken the card for 6 days, I visited pretty much everything that interested me just by showing the card. It is convenient for those who want to discover museums, attractions, monuments but if you only intend to go around Prague, it is better to pay for the few individual attractions that you are going to visit. Very convenient and integrated by an app, the Coolpass, which makes everything easier to enjoy: the app shows the map of Prague with the location of the attractions included and gives a reference description.
