Hruboskalsko is a nature reserve declared on April 22, 1998. With an area of 219.2 ha, it is one of the largest rock towns in the Protected Landscape Area Český ráj. The reason for protection is the extensive rock town with preserved relict pine forests. The Hruboskalsko rock town includes hundreds of rock massifs and individual towers reaching up to 60 m in height. Due to the low resistance of sandstone and the constant effect of various influences, the rocks are rich in a variety of shapes and forms (honeycombs, windows, gates).
