Bartosova Pec - Ondrikovicke propadani

This geological feature is one of the karst systems in limestone minerals of the Czech Cretaceous. The powerful spring for Vazovecky potok (a brook) bubbles forth from open caves about 20m long. Nearby is a former glassworks, later a mill and glass grinding workshop. Today the building serves for recreational purposes.

Bazantnik

(nature preserve)
A pond with adjacent swamp and marshy meadow. In the adjacent linden hornbeam growth is the most monumental English oak in the entire CHKO. The north-western shore has been modified as a sandy beach and brings joy to vacationers in the campground.

Jezirko pod Taborem

(natural monument)
A small, forest, marshy lake of artificial origin is forming here on the slopes of Tabor. Occurrence of a series of protected and rare species of water and marsh plants.

Jinolicke rybniky (Jinolice ponds)

This system of ponds on the north-eastern edges of Prachovske skaly is one of the most sought after recreational locations of Cesky raj. The largest pond is called Oborsky (11.4 hectares), the second is Nemecek (5.2 hectares) and the smallest pond is Vrazda (2.1 hectares). The first two are very favourable for swimming and there are small cottages and camps near it. The site is ideal for starting tours into Prachovske skaly.

Jizera

The valley of the Jizera at Semily and Bitouchov (nature preserve)
Gallery of Jizera (natural monument)
The Jizera River has its source in the Jizerske hory and when it encounters Cesky raj, it has already passed no less than 50 km through deeply cut valleys. Initially, it is in full sunlight up to the meadow beyond Turnov and its wanderings come to an end by joining the Labe near Celakovice. Between the towns of Semily and Turnov it forms a picturesque valley. The canyon section with mixed forest growth and geologically valuable rock outcroppings between Bitouchov and Podspalov was declared a nature preserve for its significant landscape-forming elements. It is accessible along Riegrova stezka (Riegr Trail), which in places leads along an iron suspension corridor, footbridges affixed to the cliffs above the surface of the river. The narrow defile through which the Jizera flows was once even narrower, but was plugged by flooding and therefore has to be artificially widened. Following along the left bank is a railway line for which it was necessary to bore a series of tunnels at a total length of 743 metres. For the hydroelectric power station in Spalov, water is collected from the river and transported in a 1300 metre long underground channel.

Klokocka

(national natural monument)
Klokocka is part of the floodplain of Bela brook along the railway line in Velky Reckov. We find here a display of glacial, relict, taiga marsh vegetation and one of two localities of Siberian ash in the Czech Republic. Animals are represented primarily by vertebrates, snails and amphibians; the predominant part of the protected territory is covered by marsh willow alder.

Komarovsky rybnik, Drhlensky rybnik

Two wonderfully situated ponds, separated by pure coniferous forests with sandstone rocks. There is pleasant bathing in both ponds and campsites at each. They are ideal bases for outings into the districts around the hill Muzsky, i.e. to Valecov, Drabske svetnicky, Prihrazske skalni mesto as well as to Kost.

Libunka

The left bank of the Jizera River. Between Trosky and Borecka skala it takes on a meandering course practically two kilometres long and then, together with semi-natural shore growth, it hosts, for example river kingfishers, river wagtails, brown frogs and wild duck.

Loucsky water system

Near Sekerkovy Loucky in the past there were nine ponds and even today the three called Cihlak, Krizak and Nohavice form the northernmost pond system in Cesky raj. Four mills have been preserved on their shores.

Podtrosecka udoli (Valleys under Trosky)

An unusually attractive tourist and recreation area in Cesky raj. Here in the 16th century, people built a system of ponds from the valley floodplain and the marshes to utilise the territory economically and today, it forms a space of extraordinary scenic and natural value. The unique canyon valley is bordered by sandstone cliffs and these also often form the shores of the ponds. We count eight of them: Vidlak with a restaurant, parking lot and campsite; Krcak; Rokytnicky and Hrudka; the shallow Dolsky, Podsemin and two of the most sought after "swimming holes" - Nebak and Vezicky pond. The Vezicky pond is located in an exquisite valley and thanks to this appealing location it has been selected several times as the backdrop for film shoots (e.g. "Jak dostat tatinka do polepsovny" [How to Get Dad into a Approved School]). Nature Preserve Podtrosecka udoli (The Podtrosecka Valley) protects the most extensive complex of marsh biotopes in CHKO Cesky raj.

Prokopske udoli - Valley of Jizera and the Gallery

A natural place of interest (125 hectars, proclaimed in 1951). A canyon-like valley with mixed woods and a geologically precious formation. For hikers it is a accessible thanks to the Riegrova path leading along the right bank of the river Jizera from Semily to Zelezny Brod. The path is partially cut in the rock and leads over a suspended iron gallery (80 meters long). The railway road on the left bank of the river Jizera leading through a set of tunnels that are 743 meters long altogether as well as the 1300 meter long tunnel on the right bank of Jizera which brings water from the weir on Jizera to the power station under Spalov are technically really interesting.

Reckov

Part of the course of Rokytka potok is in nearby Nova Ves. Occurring here are a rare post-glacial relict Siberian ash in characteristic communities (fenny and waterlogged alder).

Udoli Plakanek (Valleys and ponds by the castle Kost)

Kost castle stands on a sandstone rock at the place where three valleys meet. In the valley approaching from the north-west from out of deep forests, immediately at the castle is a small pond and beyond it in the rocks are traces of ancient inhabitants. To the north is a valley with two larger ponds. The castle is reflected in the depths of Bily, the most distant is called Cerny. The ponds played an important role in the defence of the castle. From Libosovice approaches a third pretty valley - Prokopske. After combining, the three valleys continue below the castle in the picturesque valley of Klenice brook, which is lined by sandstone rocks and is called Plakanek (The Weeper). A series of legends address the sad title, but the truth is entirely prosaic. People who burned wood for charcoal below the castle had eye diseases due to the smoke, which caused their eyes to water and therefore they were called "plakankove" (the weepers) (according to other sources, a family of charcoal-burners was even given this name). Below the spot where the valleys combine from Vesec (Vesecky Plakanek), the well Roubenka gives up its water, a favourite spot for the writer, poet and playwright Frana Sramek (1877-1952).

Vustra

This pond, which is in the valley under the former Kozlov castle, well-hidden from worldly activity, ensures basic living conditions especially for particularly protected and endangered species of marsh flora and fauna with links to meadow and pond.

Zabakor

A large pond (45 hectares) below the northern slopes of Muzsky hill. Despite an unfavourable fate - for "neighbours" it has a road, railway line and highway - it has remained a paradise for waterfowl. Swimming is not permitted here.

Zehrovka

A brook to a stream, its source in the western parts of Prachovske skaly. After 24 kilometres it empties into the Jizera River. It forms a beautiful valley, lined with cliffs and partitioned by the over one kilometre long, "thin", romantic pond Nebak, providing pleasant swimming. Below the dam stands the former Vlkuv mlyn (Wolf Mill).
