The Andean range is located in Colombia from the southwest (Ecuador border) toward the northeast (Venezuela border) and is divided in the [[Colombian Massif]] (''Macizo Colombiano'') in three ranges ([[Cordillera Oriental (Colombia)|East Andes]], [[Cordillera Central (Colombia)|Central Andes]] and [[Cordillera Occidental (Colombia)|West Andes]]) that form two long valleys, [[Magdalena River Valley|Magdalena]] and [[Valle del Cauca|Cauca]] follow by the rivers of the same name.

The eastern half of Colombia, comprising more than half its territory, is plain and composed by [[savanna]] and [[rainforest]], crossed by rivers belonging to the [[Amazon River|Amazon]] and [[Orinoco]] basins. The northern part, called the [[Llanos]], is a savanna region, mostly in the Orinoco basin (therefore called also Orinoquía). The southern part is covered by the Amazon rain forest and belongs mostly to the Amazon basin.  It is usually called Amazonía.

At the north and west of the Andes range there are some coastal plains. The Caribbean plains at the north and the Pacific plains at the west.

A recent global remote sensing analysis suggested that there were 553km² of tidal flats in Colombia, making it the 46th ranked country in terms of tidal flat area.<ref>{{cite journal |last1=Murray |first1=N.J. |last2=Phinn |first2=S.R. |last3=DeWitt |first3=M. |last4=Ferrari |first4=R. |last5=Johnston |first5=R. |last6=Lyons |first6=M.B. |last7=Clinton |first7=N. |last8=Thau |first8=D. |last9=Fuller |first9=R.A. |title=The global distribution and trajectory of tidal flats |journal=Nature |date=2019 |volume=565 |issue=7738 |pages=222–225 |doi=10.1038/s41586-018-0805-8 |pmid=30568300 |s2cid=56481043 |url=https://www.nature.com/articles/s41586-018-0805-8}}</ref>

Colombian Pacific Plains are among the most rainy parts in the world, chiefly at the north ([[Department of Chocó|Chocó]]).

The highest mountain in Colombia is not in the Andes but in the Caribbean plain: [[Sierra Nevada de Santa Marta]] with its highest points named Pico Cristobal Colon (5775 m) and Pico Simon Bolivar (same elevation).  Other mountains in the Caribbean plain include the [[Montes de María]] and the [[Serranía de San Lucas]].

In the Pacific Plains there are other mountain formations, chiefly the [[Serranía del Darién]] and the [[Serranía del Baudó]].

In the eastern Region, there is the [[Serranía de la Macarena]] and there are formations belonging to the [[Guyana Shield]].
