Cesky Krumlov is just a wonderful place. I have never tired of visiting this place. I have probably been there at least ten times, from my early twenties as a bachelor with friends, on a beer-heavy weekend in winter in a hostel, to a day trip with my kids and my mother in the summertime. There is always something nice to do.
Unrivalled even among UNESCO world heritage sites. This 700 year-old village is still full of alchemy. With a river looping around twice, you can't help but walk around in circles all day in amazement.
