The Sierra Madre del Sur (Spanish for "Southern part of the Mother Range") is a mountain range. It is in Mexico, Honduras, and Guatemala.
The Sierra Madre del Sur is about 620 miles long (1000 km) and runs northwest-southeast along the south coast of Mexico. It touches the Trans-Mexican Volcanic Belt. Its highest mountain is 12,149 feet (3703 meters) above sea level.
There are pine-oak forests and cloud forests in the Sierra Madre del Sur. Many animals and plants live there. Scientists call this biodiversity.
