Landlocked in the heart of Europe, the Czech Republic is a small territory in size but surprisingly complex in its geography. Ring-shaped reliefs, plateaus carved by valleys, river networks flowing towards three different seas, a transitional climate, a mosaic of ecoregions… the country condenses a large part of Central European landscapes into less than 80,000 km². Understanding its geography is also understanding why Prague has long been a center of power, why brown coal remains so present in the landscape, or why some border regions remain sparsely populated.
A Crossroads Country at the Heart of Europe
The Czech Republic occupies a central position on the European continent. Its coordinates revolve around 49°45′ north latitude and 15°30′ east longitude, with a territory stretching approximately between the 48th and 51st parallels north and the 12th and 19th meridians east. It shares nearly 2,000 km of land borders with four neighbors: Germany to the west, Poland to the north and northeast, Austria to the south, and Slovakia to the southeast.
Total area of the Czech Republic, including over 2% of inland waters.
The modern state is based on a different administrative organization, with thirteen regions and the capital Prague having a special regional status. These regions—from Central Bohemia to Moravia-Silesia—are further divided into 76 districts and over 6,200 municipalities, reflecting a very fine local network. But beneath this contemporary administrative grid, the country’s physical structure remains largely determined by two major units: the Bohemian Massif, a very stable old crystalline shield, and the more recent border of the Western Carpathians to the east.
Relief: A Plateau Surrounded by Mountains
The first surprise when looking at a physical map of the Czech Republic is to realize that it is neither a fully alpine country nor a great plain. The dominant landscape is one of hills, rolling plateaus, and intramontane basins, surrounded by a belt of moderately high mountain ranges.
Most of the territory is situated above 200 m in altitude, with large portions exceeding 1,000 m, especially along the borders. The highest point, Mount Sněžka (1,603 m), is located in the Giant Mountains (Krkonoše), the highest part of the Sudetes, on the northeastern border with Poland. Conversely, the lowest point is at the Elbe River at 115 m.
Bohemia is a vast, slightly convex basin, drained by the Vltava and Elbe rivers. It is surrounded by mountain ranges forming its natural borders: the Bohemian Forest (Šumava) to the southwest, the Ore Mountains (Krušné hory) to the northwest, and the Sudetes (including the Krkonoše and Jeseníky) to the north and northeast. Its center consists of an alternation of plateaus, basins, and low hills.
Moravia, to the east, has an even more hilly relief. It is structured by the Bohemian-Moravian Highlands which physically separate Bohemia and Moravia, followed by a series of medium chains and hills, such as the Moravian-Silesian Beskids, the White Carpathians (Bílé Karpaty), and the Javorníky. It is also in Moravia that the famous “Moravian Gate” is located, the broad valley of the Oder River which opens a natural corridor between the Danube Basin and the plains of Poland.
A Subsoil of Ancient Massif
Geologically, almost the entire country rests on the Bohemian Massif, an old Hercynian shield composed mainly of igneous and metamorphic rocks. Gneiss is very widespread, signs of an ancient tectonic history. At the northeastern margin of Bohemia, large formations of sedimentary rocks appear, notably spectacular sandstones, which gave rise to landscapes like the Elbe Sandstone Mountains (Labské pískovce)—known on the Czech side as “Bohemian Switzerland”—or the “rock towns” of Adršpach-Teplice.
To the east, the younger Western Carpathians form a folded and elevated border. Their relief, although lower than that of the high alpine mountains, is sufficiently marked to clearly influence the climate, water flow, and human settlement of the region.
A Country at the Summit of European Basins
The Czech Republic has no coastline, but its territory plays a key role in the European hydrographic system. It forms part of the “Roof of Europe“, i.e., a watershed area where rivers depart towards three different seas: the North Sea, the Baltic Sea, and the Black Sea.
Approximately two-thirds of the Czech territory drains towards the North Sea via the Elbe. This area roughly corresponds to Bohemia. The remaining third is primarily divided between the Morava (and thus Danube) basin towards the Black Sea, mainly in Moravia, and the Oder basin, oriented towards the Baltic, in Czech Silesia and a small part of the north of the country.
A symbolic point materializes this triple divide: Mount Klepáč, in the Králický Sněžník mountains near the Polish border. Nearby, a marker indicates the three drainage directions at approximately 50°09′ north latitude and 16°47′ east longitude.
The Four Major Structuring Rivers
Four major rivers dominate the country’s hydrographic network: the Elbe (Labe), the Vltava, the Morava, and the Oder (Odra). Each has its own logic, its figures, and associated landscapes.
The Vltava, with a length of 430 to 431 km, is the longest river entirely located in the Czech Republic. It drains a basin of over 28,000 km², covering more than a third of the national territory and over half of Bohemia. It originates in the Šumava from the confluence of the ‘Warm Vltava’ (Teplá Vltava), coming from Mount Černá hora, and the ‘Cold Vltava’ (Studená Vltava). Its course is marked by a significant drop, descending from about 1,170 m at its source to 155–156 m at its confluence with the Elbe at Mělník, a loss in altitude of over 1,000 meters.
Along the way, the Vltava flows through Český Krumlov, České Budějovice and then Prague, where it spreads into a broad ribbon crossed by 18 bridges. In total, it flows for 31 km within the capital’s limits. The river was once a direct source of drinking water for Prague; since this direct intake stopped in 1912, a treatment plant in Podolí remains ready to take over if needed. The Vltava is also heavily anthropized: nine large hydroelectric dams punctuate its course south of Prague, including Lipno, Orlík, Slapy, and Štěchovice. Lipno forms the country’s largest reservoir by area (nearly 4,870 ha), while Orlík is the largest by volume (approximately 716 million m³).

The Morava, with a length of 269 to 284 km in the Czech Republic, drains nearly 28% of the territory towards the Danube. Its basin covers about 26,600 km², with an average discharge around 65 m³/s. It leaves the country at Lanžhot to join the Danube at Bratislava. Its valley is at the heart of human settlement in Moravia and hosts vast agricultural areas: about 60% of the basin is cultivated, 32% forested, and barely 1.5% urbanized. The climate there is more markedly continental than in the west of the country, with average annual precipitation around 635 mm, rising to 1,200 mm in mountainous sectors.
The Oder rises in Moravia-Silesia, flows for 136 km in Czech territory before passing into Poland. Its total basin, largely shared with Poland and a small part of Germany, covers nearly 119,000 km² and leads it towards the Baltic Sea. It is fed by many Czech tributaries like the Opava, Moravice, and Ostravice.
The Oder, a Central European River
To give a comparative idea of these major rivers, they can be summarized as follows:
| River | Length in the Czech Republic (km) | Total Basin (km²) | Average Discharge (m³/s) | Destination Sea |
|---|---|---|---|---|
| Vltava | ~430–431 | ~28,090 | ~151 | North Sea (via Elbe) |
| Elbe (Labe) | ~370 | ~144,055 | ~308 | North Sea |
| Morava | ~269–284 | ~26,658 | ~65 | Black Sea (via Danube) |
| Oder (Odra) | ~136 | ~118,861 | ~48 | Baltic Sea |
Rare Lakes, Ubiquitous Reservoirs
The relief and geology did not favor the formation of large natural lakes in the Czech Republic. Naturally occurring bodies of water are rare and often modest. The largest and deepest of them, Černé jezero (“Black Lake”), in the Šumava, covers only 18.4 hectares.
On the other hand, artificial water bodies are everywhere. As early as the 16th century, South Bohemia saw the development of a sophisticated system of fishponds around Třeboň, including the famous Rožmberk pond (nearly 489 ha), still the largest pond in the country today. In the contemporary era, hydroelectric dams on the Vltava and other watercourses have multiplied reservoirs, which serve for energy production, flood regulation, water supply, local navigation, and recreation.
In total, there are over 125 significant artificial reservoirs, which profoundly shape the landscape, especially in South Bohemia and along the major rivers.
A Transitional Climate, Between Atlantic and Continental
The position of the Czech Republic, far from the seas but not completely isolated from Atlantic influences, gives it a temperate mixed climate, halfway between oceanic and continental. The temperature range between winter and summer is marked, winters are cold, summers relatively warm, and the weather remains variable all year.
Maritime air masses from the west often dominate, bringing moisture and relative mildness, but they can be supplanted, depending on the situation, by drier and colder flows from the continental east or, more rarely, by surges of Mediterranean air from the south. This interplay of influences is seen in the seasonal distribution of temperatures and precipitation.
Cold Winters, Warm and Stormy Summers
Between December and February, temperatures frequently drop below 0 °C. Deep cold spells can plunge the mercury towards –20 °C or even –25 °C in some valleys or plateaus. The absolute record, measured in Litvínovice near České Budějovice, reached –42.2 °C. Snow is common in winter, particularly at higher altitudes, where it can lie on the ground for several months.
Spring (March to May) is a capricious season, with risks of late frosts and snowfalls until April. It is generally only from the second half of May that temperatures become milder. Summer (June to August) offers pleasantly warm days, with average highs of 24 to 26 °C in July and August in lowland regions. Heatwaves exceeding 30 °C are frequent, particularly in Moravia, and peaks above 35 °C are not rare. The national heat record, set at 40.4 °C, was recorded in Dobřichovice, near Prague.
These summer heatwaves are often accompanied by late-day thunderstorms, sometimes violent, especially in July, which is often the wettest month. Autumn usually begins with a mild and stable period in September, before gradually becoming cooler, cloudier, and rainier until November.
Moderate Rainfall, but Very Contrasted Depending on Relief
Overall, the Czech Republic is not a particularly humid country. In plains and hills situated between 200 and 500 m in altitude, average annual precipitation often oscillates between 400 and 500 mm. The capital, Prague, receives on the order of 500 to 587 mm per year. Winter is the driest season there, with the main water input concentrated in late spring and especially in summer in the form of showers and thunderstorms.
The annual precipitation total, in millimeters, that can be exceeded in mountain ranges like the Krkonoše in the Czech Republic.
The average annual sunshine varies around 1,670 to 1,840 hours, placing the country above some major cities in Western Europe like London or Paris. In summer, one can count up to eight hours of sunshine per day on average.
Regional Variations: Prague, Moravia, Mountains
Unsurprisingly, the main internal climatic differences are due to altitude and geographic location. In lowlands, between 200 and 500 m, the climate remains relatively homogeneous: cold but not extreme winters, pleasant to warm summers, moderate rainfall. Prague, situated between 180 and 400 m, illustrates this regime well: average January temperatures between –1 °C and +0.1 °C, and July averages around 18.5 to 19.9 °C.

Ecoregions, Forests, and Biodiversity
Despite its modest size, the Czech Republic is situated at the junction of several major biogeographic units. Phytogeographically, it belongs to the Central European province of the vast circumboreal region that encircles the northern hemisphere. The WWF divides its territory into four major ecoregions: Western European broadleaf forests, Central European mixed forests, Pannonian mixed forests, and Carpathian montane conifer forests.
Approximately 34% of the territory is covered by forests. Mountain regions are dominated by conifers (especially spruce), sometimes planted intensively. At medium altitudes and in plains, stands are more mixed or deciduous (beech, oak, ash, maple). Remnants of natural grassy steppes survive in some areas of low Moravia, testifying to a past drier climate.
This forest and grassland mosaic is home to a varied fauna. Deer, wild boar, and foxes are among the common mammals, but more discreet or threatened species are also present, such as lynx, wolf, or bear in a few border ranges. Rivers and wetlands host otters, martens, and sensitive aquatic species like the freshwater pearl mussel, threatened on a European scale. The sky is sometimes occupied by large birds of prey: eagles, ospreys, kites, or emblematic species of open environments like the bustard. Storks, finally, remain strongly linked to the rural imagery of certain regions.

National Parks and Large Protected Landscapes
The Czech Republic has established a comprehensive system of protected areas governed by a specific law on nature and landscape (Act No. 114/1992). It distinguishes large spaces—national parks and protected landscape areas—and a large number of smaller sites with more targeted status (nature reserves, natural monuments, etc.).
Four national parks cover about 1.5% of the territory. In addition, there are 27 protected landscape areas (PLA) which represent nearly 14.6% of the country’s surface area. This results in a substantial network where about 16% of the territory is under official protection, not counting other instruments like nature parks or remarkable trees.
The Four National Parks
The oldest, Krkonoše National Park, was established in the 1960s on the Czech part of the Giant Mountains. It protects complete altitudinal zones, from foothill broadleaf forests to subalpine heathlands, through beech-fir forests and then montane spruce forests. It features glacial cirques, boulder fields, high-altitude peat bogs, and fragments of lichen tundra. The park is also the source of the Elbe and hosts the country’s highest waterfall, the Pančava waterfall, cascading about 250 m. The whole has been recognized as a UNESCO biosphere reserve.
Šumava National Park, the largest Czech national park, extends over nearly 685 km² in the Bohemian Forest.
Further to the southwest of Moravia, Podyjí National Park protects a spectacular river canyon carved by the Dyje (Thaya) between Znojmo and Vranov nad Dyjí. It is the smallest national park in the country, with about 63 km², but its topographic confinement creates a mosaic of slopes, dry grasslands, forest-steppes, rocky slopes, floodplain meadows, and alluvial forests that foster remarkable biodiversity. Dozens of orchid species, over 150 bird species, and about 65 mammal species are recorded there. It forms a cross-border complex with the Austrian Thayatal Park.
North of Děčín, Bohemian Switzerland National Park (České Švýcarsko) protects a unique sandstone landscape with gorges, plateaus, rock pillars, natural arches, and fault labyrinths. It is famous for Pravčická brána, the largest natural sandstone arch in Europe (approximately 16 m high and 26 m wide). This region, the Czech extension of the Elbe Sandstone Mountains, has also served as a film location.
The Major Protected Landscape Areas
Beyond the national parks, a network of 27 protected landscape areas (CHKO) covers the main natural regions of the country: “Bohemian Paradise” (Český ráj) and its rock towns, karsts like the Moravian Karst (Moravský kras) with the famous Macocha Abyss (over 138 m deep), mountains like the Beskids, Jizera Mountains, Jeseníky Massif, or the White Carpathians.
These vast perimeters aim to preserve both natural qualities and traditional cultural landscapes, such as forests, pastures, fields, old villages, ponds, and flowering meadows. Their management, planned for the long term, seeks to integrate environmental conservation, agricultural and forestry activities, tourism, and local life.
Human Geography: Contrasted Densities, Structuring Cities
With just over 10.7 million inhabitants on 78,871 km², the Czech Republic has an average density of about 134 to 138 inhabitants per km², higher than the European average. This average, however, masks strong regional disparities.
The highest densities are logically in and around the major metropolitan areas. The metropolitan region of Prague brings together over 2.2 million inhabitants on just under 4,830 km², with a density close to 470 inhabitants per km². Ostrava forms another very dense pole in the northeast, with nearly one million inhabitants in its metropolitan area. Conversely, some mountainous border zones, especially along the German-Czech and Austrian-Czech borders, remain sparsely populated. This underpopulation is partly explained by history: the expulsion of the German-speaking population after World War II emptied many municipalities in these regions, and demographic dynamics have not fully filled this void.
The Prague region had approximately 1.39 million inhabitants in 2024.
Urbanization is high: around three-quarters of inhabitants today live in urban areas, although estimates vary (about 67% according to some sources, 75% in other projections). Prague overwhelmingly dominates the urban system, followed by Brno, Ostrava, Plzeň, and Liberec.
Major Cities in Their Physical Setting
Prague, located in the heart of Bohemia on the Vltava, illustrates well the interplay between relief, river, and urban development. The city spreads over hills between 180 and 400 m in altitude, carved by lateral valleys flowing into the river. This rugged terrain strongly structures neighborhoods, vistas, and transportation infrastructure.
Brno extends over an area of about 230 km², of which 28% is forested.
Ostrava, the third city and heart of Moravia-Silesia, is situated in the alluvial plain at the confluence of four rivers—Oder, Opava, Ostravice, and Lučina—on the edge of the Moravian Gate. Its altitude remains modest (highest point around 280 m), but proximity to the Silesian ranges and coal basins gave it a major industrial role, at the cost of lasting environmental impacts. Today, the city seeks to enhance its rare alluvial forests, like those of Polanský les, integrated into the Poodří protected area.
Other cities like Plzeň, Liberec, or České Budějovice maintain a close relationship with their immediate environment: Plzeň at the confluence of several rivers in West Bohemia, Liberec at the foot of the Jizera Mountains, České Budějovice in the heart of the South Bohemian pond country.
Natural Resources and Their Impact on Landscapes
The Czech subsoil is rich in mineral resources, particularly coal, lignite, and construction materials. Historically, the exploitation of these resources has profoundly transformed certain regions, especially in the northwest.
Presentation of the major lignite extraction regions and their impact on the landscape.
The largest deposit, located at the foot of the Ore Mountains. Covers about 1,400 km² around the towns of Chomutov, Most, Teplice, and Ústí nad Labem. Characterized by immense open-pit mines operated by companies like Severoceske doly.
A deposit located further west than the main North Bohemian Basin. Part, along with other more modest deposits, of the country’s lignite resources.
Exploitation has created spoil heaps, pits, reclamation lakes, and artificial plateaus. Many sites are reforested or renaturalized after mine closure.
Further east, the Ostrava-Karviná basin, part of the great Upper Silesian coal basin, was the other major coal pole, mainly for hard coal. Here too, underground mining left a strong imprint on the urban and peri-urban landscape, with many spoil heaps, mining infrastructure, and industrial zones.
Small quantities of oil and gas are extracted in South Moravia, but the majority of consumed hydrocarbons are imported. The country also has other resources like uranium, graphite, kaolin, and tin, whose exploitation historically influenced employment and urbanization in certain regions.
This intense exploitation necessarily has an environmental cost. Soil restoration, reclamation of former mining sites, management of polluted waters, and greenhouse gas emissions are among the major challenges linked to this geography of resources. The fact that about 40% of the electricity produced in the country still comes from lignite combustion illustrates the tension between mining heritage, energy security, and climate objectives.
Agriculture, Water, and Land Use
Approximately 37% of Czech territory is considered arable land. These agricultural areas are concentrated mainly in plains and alluvial valleys, notably along the Elbe and Morava, where soils are deeper and slopes gentler. At the scale of the Morava basin, about 60% of the land is devoted to agriculture, making this region one of the country’s main breadbaskets.
Estimated area of land equipped with artificial irrigation systems at the national level.
Between agriculture, forests (34% of the territory), urban areas, and mining or industrial surfaces, the land use map depicts a country where plains and valleys are intensively exploited and where reliefs still serve as refuges for more natural ecosystems, even though tourism pressure and forest monocultures are very real there.
A Dense Transportation Network in a Landlocked Country
Despite the lack of a coastline, the Czech Republic plays a central role in European circulation. Its position at the crossroads of east-west (Germany–Slovakia) and north-south (Poland–Austria) axes has made it a hub where roads, railways, and waterways densify.
The road network comprises over 55,000 km of roads, including about 1,250 to 1,500 km of motorways. The latter form a star-shaped network around Prague and connect major cities to neighboring countries. Speed limits are set at 50 km/h in built-up areas, 90 km/h outside built-up areas, and 130 km/h on motorways, with sections where the maximum speed can be raised to 150 km/h.
The Czech railway network, about 9,500 km long, is one of the densest in the world in terms of track length per km².
Finally, while inland navigation remains limited, certain sections of the Elbe and Vltava are developed for barges of 300 to 1,000 tons, notably between Mělník and Prague. In a legal curiosity inherited from the Treaty of Versailles, the Czech Republic still has, until 2028, a small port territory right in the port area of Hamburg, the Moldauhafen, intended to guarantee it technical access to maritime connections.
A Strongly Structuring Geography
At the end of this journey, what strikes one about the geography of the Czech Republic is the coherence between physical forms, history, and human organization. The old Bohemian Massif, the coal basins of the northwest and northeast, the agricultural valleys of the Elbe and Morava, the protective yet isolating mountain belts, the crossroads position at the summit of three major river basins: all elements that explain both the distribution of populations, industrial concentration, vulnerability to floods, and the richness of protected landscapes.
The geography of the Czech Republic has directly influenced the location of its cities, often situated near waterways, like Prague on the Vltava, Brno at the meeting of two rivers, and Ostrava at the confluence of four rivers. It has also shaped transportation axes, resource exploitation, and preserved remarkable natural spaces such as the Šumava forests, the Dyje gorges, the sandstone rocks of Bohemian Switzerland, and the Moravian karsts.
In a context of climate change, energy transition, and increasing tourism pressure, this same geography places the Czech Republic before delicate choices: reducing dependence on lignite without destabilizing mining regions, protecting already highly artificialized forests, preserving waters of sensitive basins like the Morava’s, all while continuing to make this small country of plateaus and mountains a vital node at the heart of Europe. A fine understanding of Czech geography, far from being a mere academic exercise, thus becomes an essential tool for thinking about its future.
