Cesky Krumlov
One of the prettiest towns in Czech!
If you want to get out of the hustle and bustle of Prague, this place is a must visit. Around 2.5 hours away from Prague, the town can be covered in a day trip. The castle offers spectacular views of the town. The entry inside the main castle is chargeable however, the entry to the gardens is free and worth every step you walk. There is a square in the center of the town which is pretty to sit across and relax.
