The very first protected landscape area in our country was declared in 1955 just within the area of Český Ráj.

The territory of Český Ráj comprises a wide range of geological phenomena: it is, in fact, a real geological atlas. Therefore, in October 2005 it was added to the list of the European Geoparks Network.

It is situated at the platform of Hruboskalsko, at the Golden Trail of Český Ráj, not far from Hrubá Skála Castle.

Karlov, a local part of Lomnice nad Popelkou, was declared a folk architecture preserve.

Bažantník is a nature preserved pond with marshy meadows. It was declared in 1998.

The geomorphologically attractive canyon formed by the right bank of the Jizera River is located two kilometres to the southwest from Mnichovo Hradiště. Because of the river erosion, well washed-out banks and chambers have been formed in the otherwise lime rock.
