"For a day trip I recommend Kutná Hora: the Sedlec Ossuary is famously creepy with some 40,000–70,000 bones (the church visit only takes about 15 minutes), and the town’s medieval center has marvelous churches and well-preserved streets that feel like a less crowded version of Prague; skip-the-line tickets with an audio guide cost 200 CZK." - Matthew Kepnes
