What to do in Prague for 3 days
Day 1, discover the Old Town of Prague
Start in the center of the old town, the Old Town Square with the most famous Astronomical Clock (the maker of it was blinded not to make some for anyone else), and all kinds of festivals (if Easter or Christmas time).
Wonder around the old streets, nice architecture, cafes and pubs (Czech beer is world famous). Do not forget to taste some local cuisine.
Wenceslas Square is an enormous long square lined with retailers that you can find nearly anywhere in Europe, capped with the National Museum. This is the center point of much of the revolutionary history of the city. The Velvet Revolution, which lead Czechslovakia split and the end of communist regime had began here.
Visit the Jewish Museum in Josevov the jewish quater of Prague. Guided tour available.
As you are wondering around, check the river of Vltava and some historical and not that histroical, but well known (like the dancing house) next to the river.
Find a cosy, not that fancy restaurant for a nice czech dinner, have a beer for good night sleep.
Day 2, the Castle Hill
The Castle of Prague located on the other side of Vltava river, so cross it on the most famous part of Prague, the Charles Bridge.
Charles Bridge is a pedestrian only bridge that crosses the Vltava River. The spiked towers on either side were used as models to rebuild several of the other towers in town during the Victorian era. This is definitely a worthwhile site to stroll over.
The bridge usually full with musicians, artists and tourists, so can be a bit crowded. Try early morning.
It is free of charge to get into the Prague Castle, but you have to pay for exhibitions's visit.
Major sight of the hill include St Vitus Cathedral, whose towers dominate the skyline of the hill, and you can climb one of the towers. A row of old low houses called the Golden Row (Zlatna ulicka) once housed the city’s famous author son, Franz Kafka (for 2 years). The street got its name after the goldsmiths whom lived here in the 17th century.
Day 3, daytrip from Prague
There are many places to go for a daytrip from Prague, see the Church of Bones in Kutna Hora, see the birthplace of Plzen beer in Pilzen, but the most popular is the discovery of Cesky Krumlov.
Cesky Krumlov is about 1 hour away from Prague, a hidden gem, a leftover from the 17th century. The old town is almost a total wonder of old houses, mills, pubs, squares. You can find the second biggest castle in the Czech republic and a theatre from the medieval times. Do not miss it! Oh, yes it is an UNESCO Site.
