There are a number of sites that list places of tourist interest in Czech Republic. As for me, visiting 10+ castles doesn’t make sense, so here is the “balanced” list of places you should see in Czech Republic.
1. Center of Prague
You won’t miss this. Take any map in tourist office and walk around. The best way is to use public transport.
Take a metro red line C to the station “Vyšehrad”. Go out there and follow direction signs or ask for direction to Vyšehrad. Worth seeing, one of the best views of the Prague, especially in the night.
3. Křižíkova fontána in Prague
Great fountain and music show in the night (shows run at 20, 21 and 22 p.m.).
4. Hrad in Hluboká nad Vltavou
Beautiful caste in the South Bohemian. Looks great from outside and inside in comparison to other castles in Czech Republic.
5. Český Krumlov
Small city, not far away from Hluboka, it is located in the South Bohemian. Added to Unesco World Heritage list, diffenetly worth seeing.
6. České Švýcarsko.
České Švýcarsko National Park - pure nature. More information with photos will be added
7. Hrad Karlštejn.
This castle is a very popular place, because it is not far from Prague, diffenetly worth seeing.
