The mountains are classified in three big chaines, because of their heights, geological structure and layer:

1 East Carpathians

East Carpathians lies between north country border and Prahova River Valley to south: has the second place as height between the romanian Carpathians with a media of 1600-1700m, the highest reaching 2303 (M.Rodna). They represent the largest mountain group and has as specific characteristics the parallel disposal of ranges in three lines:
-the west line: here are the vulcanic (dead) mountains smaller in north (M.Oas, M.Tibles, M.Gutii) and higher in the south (M.Calimani,M.Gurghiu,M.Harghita);
-the midlle line: here are the highest mountains in the group (M.Rodna,M.Suhard,M.Maramures) which decrease meeting Trotus River Valley;
-the east side: here are the smallest mountains and they occupy the whole south of East Carpathians.
They divides into three groups:
a)North Group which has the mountains disposed on two sides: west side, higher, and east side, smaller;
b)Central Group which has also the mountains divided into two sides(west and east); the west, the vulcanic areal is separated by the east through 2 big depressions; the east are known as Moldavia Mountains and are disposed on 3 parallel ranges, the central range being the highest also (M.Bistrita,M.Ceahlau,M.Tarcau);
c)South Group are large mountains, the highest, also a touristic atraction are Ciucas Mountains (1954m); they surround a big depression with the name of the well-known town, Brasov.
 Climate The East Carpathians has a mountain climate with the annual media between 0-6 degrees, 800-1200mm as a precipitation media, and register very decreased temperature during winter time in the depressions.

2 Middle Carpathians

Middle CarpathiansThese are the highest mountains in romanian Carpathians, with a medium height of 2000m, reaching 2500m in many places. They lies bewteen Prahova River Valley to east and Timis-Cerna Valley to west. As specific characteristic, there are flat, large platforms at big heights (1000-2000m) used in summer time by ships. One of them kept the marks of dacic culture from the beginning of the first milleniun (The Sarmisegetuza Regia fortress in Orastie Mountains (north of Sureanu). Another characteristic are the marks of former glaciation which can be seen in relief shapes and the numerous lakes from the tops. They divides in 4 big compact groups function of the river valleys crossing them:
a)Bucegi Group, the most visited by tourists because of the existance of many resorts and accommodations too;
b)Fagaras Group the most beautifull, wildest place, with the highest mountains in Romania (2544m);
c)Paring Group;
d)Retezat-Godeanu Group where is the National Park of Retezat, one of the protected areals in Romania.
 Climate The Middle Carpathians has a mountain climate with the annual media between 0-6 degrees, 800-1200mm as a precipitation media, and register very decreased temperature during winter time in the depressions.

3 West Carpathians

West Carpathianshas a medium height of 1000-1400m being the smallest mountains in the romanian Carpathians; they lies between Danube Valley to south and Barcau Valley to north. As a specific characteristic there is the big fragmentation and discontinuity of the mountains, the depressions and river valleys entering deep into the mountains. They are divided into 3 big groups:
a)Banat Group, reaching the highest at 1446m;
b)Poiana-Rusca Group reaching the highest at 1374m;
c)Apuseni Group has several protected areals too because of the multitude of caves, river keys; in the south of the group lies "Gaina" Mountains where is annually organized "Girls Market Fair", today is only a celebration of an old tradition, but on the old times girls used to get married there;
 

Climate The West Carpathians has a varied climate, with varied temperature, such as the mountain climate could be found only on parts of Apuseni and Poiana Rusca (0-6 degrees annuall media), but the temperatures are a bit higher than in the other Carpathians because the mountains are smaller and has oceanic influences with rains and moderate temperatures ; most of them has a warmer climate, the climate for hills (6-10 degrees annuall media); the precipitations annuall media is of 1000-1200mm; in the south, Banat Group has submediteranean influences with heavy rains in automn and soft winters.

4 Transylvania

Transylvania The three mountains chanes surround a big depression - Transylvania. It consists of two areals:
-the areal of submountains depressions and hills as a path between the big mountains and big depression with height between 400-1000m;
-the table-land areal (with medium height of 500-600m) divided into three units function of river valleys:
a)Tirnavelor Tableland, in north of Middle Carpathians and south of Mures River Valley;
b)Transylvania Field between Mures River Valley in south and Somes River Valley to north;
c)Somese Tableland between Somes River Valleys in south and west hills to north;
 Climate Transylvania has the "hills climate" (6-10 degrees temperature annuall media), with 700-1000mm precipitations in submountains hills and depressions areal and 500-700mmm precipitations annuall media in table land areal; has oceanic influences which bring humidity and moderate temperatures.

5 Subcarpathians

Subcarpathians They surround the Middle and East Carpathians at the outside borders; they reach between 300-1000m and are the paths between mountains and tablelands. The Subcarpathians are divided into three units:
a)Getic Subcarpathians,between Motru W and Dimbovita E River Valley; they represent the path between Middle Carpathians to Getic tableland;
b)Curburii Subcarpathians between Dimbovita S and Trotus N River Valley; they are a path between the mountains (Middle and East Carpathians) to Romanian Field; they reach the highest altitude between the romanian Subcarpathians (500-100m);
c)Moldavia Subcarpathians lies between Trotus S and Moldavia N River Valleys;
 Climate They have a "hills climate", with 6-10 degrees annuall temperature media, 700-100mm annuall media of precipitations;

6 Tablelands

Tablelands There are 3 important romanian tablelands:
a)Getic Tableland,lies south to Getic Subcarpathians; reaches between 225m south to 745m north; ;
b)Moldavia Tableland lies east of Moldavia Subcarpathians, reaching between 190-587m;
c)Dobrodgea Tableland lies in the south east of the country and is treated below this at point 7;
 Climate They have a climate for smaller hills with 500-700mm annuall media of precipitations for Getic Tableland and part of Moldavia Tableland and 400-500mm annuall media of precipitations for the east and south of Moldavia Tableland ; they have submediteranean influences in the west side of Getic Tableland, transition influences (from submediteranean and oceanic to aridity) for the rest of Getic Tableland and aridity influences for Moldavia Tableland

7 Dobrodgea

Dobrodgea lies in the south east of the country between Danube River and Black Sea Coast; it is structured into two areals:
a)The south areal (made of three small tablelands which reach between 100-200m); the areal is crossed by Danube-Black Sea Chanel, an artificial chanel linking the Danube River to Black Sea;
b)The north areal is higher (200-467m) representing the rest of mountains much older than Carpathians.
In the north and east of Dobrodgea lies Danube Delta; this is another natural rezervation of the country declared also "natural rezervation of biosphere". Has an areal of 4340 km square and is considered one of the first most important deltas in Europe; it is an interesting touristic areal. On the east side of Dobrodgea Tableland and south of Razim Lakes Areal (part of Delta) lies the famous touristic coast of Black Sea with a chain of resorts starting from Navodari to south border Vama Veche.
 Climate The tableland has a climate for fields with 10-11 degrees annuall temperature media, few rains (under 400 mm annuall media) and two kinds of influences: oceanic influence on the coast and few kilometers inside the tableland, with soft winter and cooler summers and the main influence, for the rest part of tableland, is aridity with hot summers, litlle rains and freezing winters.

8 West Field and West Hills

West Field lies in the west of the country, at east from West Carpathians; has an altitude of 85-143m and several subunits; the path between the mountains and this field is done by West Hills with very small altitude (about 300m or less);
 Climate Has the climate for fields with 10-11 degrees annull media, 500-700mm annuall media of precipitation for field and 700-1000mm annuall media for the hills; has the wet and soft oceanic influences.

9 Romanian Field

Romanian Field lies in the south-east of the country; here is the capital of the country, Bucharest. At south at east flows Danube River which is the border with Bulgary also.
 Climate Has the climate for fields with 10-11 degrees annull media and a varied range of influences:
-submediteranean in the west;
-transition (from submediteranean and oceanic to aridity) in the center;
-aridity in the east;
The annuall media of precipitations is decreasing from west to east from 500-700mm in the west side to less than 400mm in the east side.
