The Eastern Cordillera of Colombia is the widest and most extensive of the three branches into which the Cordillera de los Andes is divided in Colombian territory. The other two branches are the Cordillera Central and the Cordillera Occidental. It extends from the Nudo de Almaguer, or Colombian Massif, in the Department of Cauca, to the Perijá mountain range, in La Guajira.
It intervenes in the relief of the departments of Cesar, La Guajira, Meta, Tolima Huila, Cauca, Cundinamarca, Boyacá, Caquetá, Santander, Norte de Santander and Arauca. It ends with two divisions, the shortest in La Guajira and the longest in Venezuela.

South Eastern Cordillera
With numerous depressions, such as the Guacharos pass or La Ceja pass.
Central Eastern Cordillera
From the Sumapaz páramo divided into three axes, the eastern one from the Chingaza páramo and Sierra Nevada del Cocuy.
The Central axis, the Boquerón and Guasca moorlands, and the Western axis, the Tequendama waterfall and Peña de Guerrero.
North Eastern Cordillera
The Cordillera includes El páramo de Santurbán. It bifurcates towards the Motilones mountain range, and towards Venezuela. It stretches for 1,200 kilometers, being the longest and widest of the three branches. It covers an area of 130,000 km².
Upon reaching Cundinamarca and Boyacá, it widens considerably. There is the fertile savannah of Bogotá, where the Capital of the Republic is located, and other cities.
- The high Andean forest and the paramo
It has two unique habitats on the planet, the High Andean forest and the páramo. The páramos are very sophisticated ecosystems for water filtration. It is generated by the accumulation of organic matter and the morphology of plants that act like sponges.
In addition, the high content of volcanic ash in the soil makes decomposition processes slower. The moors are 3100 meters above sea level.
The Andean forest is almost always covered with fog, and with great humidity. It develops between 2800 and 3200 meters above sea level, and stands out for its biological diversity.
We find there species of trees such as raque, mortiño, encenillo, alder, cinnamon and rosemary. Also several types of ferns such as the palm fern that exceeds ten meters in height. Orchids, lichens, and moss add color and texture to these forests.
The functions that the Andean forest fulfills is to regulate the contribution of water that descends from the moors.
It accumulates and manages nutrients, facilitating the development of trees 15 to 20 meters high. Unfortunately in Colombia this type of forest is seriously threatened by logging and urban development.
Fauna
Many species of animals live exclusively in the páramos of the Eastern Cordillera. They are endemic species that are not found in another part of the world.
Among the mammals we can mention the shrew, the mouse and the curi. Of the birds we can mention the rail or tingua of Bogotá, the yellow-winged parakeet, and the Apolinar cockroach.
There are reptiles like the lizard, the collared lizard, and the earth snake. There are also numerous amphibians such as the jumping frogs, the harlequin toad, the tree frog, the hefty frog, the glass frog and the rain frogs.
Among those named, there are many species that are threatened or in danger of extinction. Some of them are the runcho mouse, red wolf, spectacled bear, tigrillo, puma, páramo tapir, soche, wolf guagua and tinajo or borugo.
There are also birds that are in danger, the rufous duck, the condor of the Andes, the crested eagle, becasina paramuna or caica, and the mountain parrot.
Virtually all of the amphibians named above are severely threatened by the destruction of their habitat.
Flora
There are more than 1500 species of vascular plants (plants with seeds and ferns) in the area. Among the trees we can mention the wax palm, the alder, the croto, the chochito, peonio or siriguay, the oak, the yellow and Manizales guayacán, the seven leather or mayos, the Andean cedar, the carnation cedar, the monde cedar, pink cedar, palo flower, rosewood, guamo bejuco, guamo rabo de mico, guamo santafereño, rubber sabanero, grape, arrayán or guava de Castilla, mountain pine or romerón, weeping willow, red drunkard or campanilla, raft, cajeto, garagay or urapo. All of these species are native.
There are also foreign species such as the araucaria, the false pepper, the ash tree, the elderberry, the Australian pine, the cypress, the castor, the magnolia, the Chinese rose, the silver mimosa, the black acacia, the eucalyptus, the urapan, Monterey pine, jasmine, cherry, black poplar and linden.

- Cave of the Guacharos
- Chingaza
- Serranía de los Yariguíes
- Sierra Nevada del Cocuy
- Natural Pisba
- Sumapaz
- Los Estoraques Unique Natural Area

Hydrography
The hydrography of the area is numerous and varied:
Magdalena river
It empties into the Caribbean Sea, is navigable, and has a tributary that is the Cauca River.
River
It empties into the Orinoco, its tributaries are the Guayabero and the Ariari.
River
Called Vicachá by the Spanish. Upon arriving in the city of Bogotá, it is channeled. Below Av Jiménez and the sixth one receives the San Agustín river. Reaching the fourth and Boyacá joins the river Fucha, always running like an underground river.
River
It is born in the Chingaza moor at 3,500 meters above sea level. Run for 137 km through a deep canyon. It is divided in two in a section, called the Negrito river, until it converges with the Meta river. It empties into the Humea River.
Bogota River
it is neither navigable nor mighty. It empties into the Magdalena River. It runs through 380 kilometers and is highly polluted.
Arauca River
Part of its route is the border with Venezuela. It empties into the Orinoco River already in the neighboring country.
Meta River
It is one of the tributaries of the Orinoco. During its journey and for 220 kilometers it forms another part of the border with Venezuela. Almost 80% of its course is navigable.
Suarez River
It ends in the Sogamoso, which in turn does so in the Magdalena. It is born in the Laguna de Fúquene, and on its way it receives the Fonce river.
Catatumbo River
It empties into Venezuela at Lake Maracaibo. It is born in the Cerro de Jurisdicciones at 3850 meters above sea level.
Zulia River
It is a tributary of the Catatumbo and travels 310 kilometers. It is born from several streams in the Cachirí páramo.

Orteguaza River
It is born in the Eastern Cordillera, and runs for 130 km, all navigable. It empties into the Caquetá river.
Caguán River
It is born in the Eastern Cordillera. It joins the Caquetá river.
Tunjuelo River
It is born in the Chisacá reservoir. It is a tributary of the Bogotá River.
Río Fucha or Río San Cristóbal
It is born in the Cruz Verde moor and flows into the Bogotá River.
Chicamocha River
It is born at the confluence of the Tuta River and the Jordan. It joins the Suárez river and the Fonce. flows into the Sogamoso.
