Český ráj (Bohemian Paradise) is a protected area declared in 1955 as the first nature reserve in the Czech Republic. It is situated in the north of Bohemia and north-eastward from the Prague. One of the most recognizable elements of the Bohemian Paradise are rock towns, which have been shaped by wind, water, frost, erosion, and humans into unique and curious shapes. The area is well-known also thanks to a beautiful and varied countryside. There are a lot of places which should be seen here - castles, ruins, museums, and other sights.
