Prague is the most beautiful city I have ever seen. I have been there counless times and remember the city from times before the iron courtain fall. That time you could walk alone at the mysterious old Jewish cemetery, peopleless Charles Bridge or even Zlatá ulièka. Nowadays you can avoid crowds of tourists if you go apart the main tourist routes. The historical city is big enough, so just take a city map and enjoy your walk around the quiet streets and squares.
