The Chicamocha Canyon (CHEE-kah-MOW-cha) is a steep sided canyon carved by the Chicamocha River. This river flows through the departments of Boyaca and Santander, where it reaches its maximum depth near the outskirts of Bucaramanga.
The canyon is the result of the erosion caused by water. It created deep cliffs on both sides. The Chicamocha Canyon begins near the town of Soata in the Department of Boyaca and flows mainly through the Department of Santander, extending all the way to the municipality of Lebrija. This geographic feature was caused by the movement of tectonic plates that extend from the Chicamocha canyon to other regions such as Bucaramanga.
The canyon extends over 108,000 acres and 2000 meters in depth. The canyon was formed about 46 million years ago. On this territory many million years ago, there was a lake that hosted many marine animals whose remains have been found. The canyon is currently administered by Chicamocha National Park. In 2009, the canyon was nominated as one of the 7 natural wonders contest.
