the highest peak of Bohemian Paradise is a part of Ještěd-Kozákov ridge. It was created by uplifting along the Lusatian Fault 5 million years ago and it consists of Paleozoic phyllites, rocks of Carboniferous and Permian Ages, Cretaceous sandstones, and Tertiary basalt. A body of amygdaloidal melaphyres in the Votrubec´s quarry gives the evidence of volcanic activity in the Late Paleozoic Era. Various types of quartz, agate, jasper, chalcedony, zeolites, and more crystallized in the cavities of the melaphyre. Stones from Kozákov were used already by prehistoric hunters. A tourist lodge with restaurant is on the top of the hill, with a new 40 m high publicly available lookout tower offering wonderful view of the Bohemian paradise landscape.
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 meters. Rock wall in Hradek exceptionally reach up to 20 meters. 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.
River Jizera is about 200 m deep, a canyon-like valley north from the town Semily. Bare rocks give the evidence of hundreds millions of years long history. Resistant types of rocks remained forming the rock cliffs, surrounded with areas called the "sea" of broken stones, sometimes descending to the river stream. There is a trail with a spring of A. Stašek with clean water, and several lookouts showing the river valley. A rocky canyon is hollowed-out in albitic granite massif, which rises to a height of 40 m above Jizera river on the side of Rieger's Path near Bítouchov. That's where the pedestrian gallery, 77 meters long and hanging on a rock 5.5 meters above the river level was built.
The ravine of Měsíční valley is situated in sloping layers of Korycany formation along the Lusatian fault in the foothills of Kozákov near the village Vesec. The local quarry is still occasionally used. Sandstone layers sloping to the west are exposed here. The thickness of the sandstone layers reaches up to 7.1 m. The 30 m high canyon walls are closing together and end in the formation called Vrata. Slender rocky pinnacles and caves, some of them of pseudokarst origin, such as Babí pec and Kudrnáčova pec, and others created by human hands accompany the main rocky canyon. A rich paleontological discoveries such as Ichnofossils were made in the area.
Hruboskalsko rock area consist of a distinctive up to 60 m high sandstone towers with poetic names such as Bandleader, Conductor's baton, Lighthouse, Dragon's Tooth, and Dragon's Tower, which became legendary for several generations of climbers. Honeycombs, ledges, rock windows, gates, caves and tunnels developed in many of the Hruboskalsko sandstone rock towers. Many lookouts offer a wonderful view of the area, the best known is called Virgin Mary above the Dragon rocks with castle Trosky in the distance. The deep canyon situated below the castle Hrubá Skála is the most visited, where leads a 65 m long shallow rock corridor called Mouse hole.
Rock area Klokočí consist of an asymmetrical ridge of Late Cretaceous sandstone blocks with the total length of approx. 1600 m 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.
Bartošova pec lies at the bottom of 40 m deep valley of Vazovecký stream, hollowed in calcareous rocks of the Bohemian Cretaceous Basin. The stream, fed by rainwater, runs through the cave with the length of 225 m. Ondříkovice slide (subsidence), immersion in Roudný, and Bezednice pool (name means Bottomless) are all interconnected in a unique karst system consisting of a large labyrinth of interconnected karst phenomena such as sinkholes, springs and drafts, where beautiful clear water of Vazovecky stream flows partially on the surface in cascades and also hidden under ground. The area was declared a protected natural monument in 1996.
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.
Horizontal Cretaceous sandstones were erected to almost vertical position by tectonic activity in Tertiary Period. Significant ridge with its length of 1 km is towering above Malá Skála village and it is divided into 20 rock towers, some of which reach heights of up to 80 m. Coarse-grained and partially conglomerated sandstones are variously siliphicated and ferruginizated along the fault plane. The occurrence of tectonic mirrors, strongly siliphicated tectonic ribs and a dense grid of quartz veins is unique. Suché rock, also called Cantor´s organ, are a popular tourist destination, especially among rock climbers.
Nature Reserve Apolena is situated 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.
Nature reserve with a characteristic complex of rock formations line the sandstone upland plateau Mužský near the town Mnichovo Hradiště. Most of its rocks are located on the edge of the canyon valley. There are 178 sandstone towers, from which the bizarre rock formation called Kobyla is the most known. The remnants of the rock castle Drábské světničky with the rock-hewn chapel called Hynšta hides in the rocks. A substantial portion of the area is covered by forest vegetation represented mainly by pines with the minority of oak and beech, and less by other deciduous trees.
They are located 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.
Tourists favorite 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. The area is rather small in terms of size, but its rock formations, gorges, ravines, hollows, and locations of prehistoric finds are abundant. It is protected as a nature reserve since 1933. The most interesting parts of the rocks are easily accessible on safe tourist marked paths and many beautiful lookouts provide a complete overview of Prachov Rocks area.
These beautiful karst Caves reaching a depth of 43 m and length of 1100 m, which are publicly available in a length of 350 m, were created by erosion from water leaking in irregular calcareous dolomite body with dimensions of 400 x 300 m and thickness more than 100 m. The deepest permanently flooded areas form the largest publicly accessible underground lake in Czech Republic. The structure of its underground galleries is determined by later tectonic disturbances intersecting the dolomite body.
The rock wall of white quartzite is located at Záskalí in Železný Brod (at the end of the road to the left, about 200 metres 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 metres, and it is only 2 metres wide in some places. The quartzite wall reaches the height about 20 metres in its western part.
Just outside the village of Troskovice, a couple hundred meters under Hotel Trosky. Most basic campsite imaginable. There is no reception, the owner comes by every day to collect money.
Pretty well equipped campsite on an island in the Jizera river. Since the river flows from the mountains it is perfect for cooling you down on a hot summer day.
Usually you wouldn't expect much from a rest stop restaurant, but it has actually been one of the best restaurants in the area for 25 years now.
Taboriste (basic campsite with few facilities) in a beautiful setting. Right across from the restaurant, other than that not much nearby.
The biggest and most developed campsite in the area. Right next to a little lake with a beach.
Can't go wrong here, decent pizzas and other meals, decent atmosphere, nice location.
