Karlstejn Castle is another place for a day trip in two or with a bunch of friends. Karlštejn is a Gothic royal castle and a Czech national cultural monument. Located thirty kilometers from Prague on a high limestone mountain above the river Berounka, surrounded by forests. This castle was built by Charles IV, and is surrounded by many legends. We recommend that you not only buy a tour of the castle and its courtyard, but also enjoy peaceful walks in the surroundings or sit out in the countryside – in warm weather you can also organize a picnic or go to the quarry Velká Amerika, which is a short walk from Karlštejn.
