The rock wall of white quartzite is located at Záskalí in Železný Brod (at the end of the road to the left, about 200 m behind the town swimming-pool). The rock formation is a good example of frost weathering of the Ice Age, when the "sea" of broken stones and rock wall had formed here. Its eastern part is stretched more than 50 m, and it is only 2 m wide in some places. The quartzite wall reaches the height about 20 m in its western part.
Nature Reserve Apolena is near Castle Trosky east of the village Troskovice. Rock towers were separated by erosion after fracturing of the sandstone basin. The eruption of the nearby volcano 17 million years ago, and also falling of individual blocks of rock on the hillside of Libuň furrow influenced it. Rock massive and standalone rock towers from the softer sandstone are a good habitat for rock nesting birds such as kestrel, eagle owl, and Jackdaw. Cleftcave Sklepy, the largest in the PLA Bohemian Paradise, which is the home for eleven species of bats, is hidden among the rocks.
Ridge and plateau with Besedice rocks together with downslope to the Jizera consists of two levels of rock walls, where the rock mazes Kalich and Chléviště can be found. There is a cave of Vaclav Sadovsky from Sloupno and many beautiful lookouts to view the valley of Maloskalsko. The rock block Kalich lies in the middle of five rocky canyons and hides a rocky altar with an engraved cup and year 1634. There is an extract from The Testament of Comenius, verses from The Bible and verses of a Franciscan monk J. Vitásek inscribed in the stone. An educative trail, which introduces the most important places, goes through the area.
These rocks are on the hill Bor (360 m above sea) 1 km west of the village Rovensko p. Troskami. An elongated hill is bordered with rugged sandstone wall with alcoves, ledges, cavities, and caves. The sandstone rocks of Borek include a number of interesting rock formations, such as blocks, columns, caves and various minor forms of weathering such as honeycombs and ironstones. The upper plateau is covered by pines, whose age is about 120 years. Shallow sandy soils and hard sandstone bedrock caused the vegetation to grow flat tops, slightly stunted.
Rock area Klokočí consist of an asymmetrical ridge of Late Cretaceous sandstone blocks about 1600 m long, with a large number of variously sized cavities. The vegetation includes pine forest with fragments of beech. The largest sandstone cave of Bohemian Paradise called Postojna is located here, in which the traces of the oldest settlements in the area were found. Rocky outcrops of Klokočí offer many attractive lookouts with magnificent panoramic views of the northern and south-eastern part of the Bohemian Paradise including Kozákov hill. The ruins of the castle Rotštejn lies towards the southern edge of Klokočské rocks.
The sandstone plateau located between the villages Borek, Křížky, Záborčí, and Voděrady is divided by shallow valleys and canyons into several parts, which are bordered around the edges by rock outcrops. One marked trail leads from the town Turnov around Dlask farm, another one leads roughly north-south direction along the axis of the rocky area. The lookouts showing Suché rocks, castle Frýdštejn, and the Jizera valley are excellent here. The average height of the rocks is around 10 m. Rock wall in Hradek exceptionally reach up to 20 m. Deep overhangs are common at the foot of the rocks. Suitable conditions for the emergence of rock resembling the shape of mushrooms are to be found in central and southern parts of the rocks.
Prachovské skály
Tourists' favourite rocky area represents the remnants of a sandstone plateau with deep gorges and valleys, where nature created a unique sculpture with tall, significantly extended rock towers.
