Isthmus of Tehuantepec, Geographic isthmus in Oaxaca and Veracruz, Mexico.
The Isthmus of Tehuantepec is a land bridge in southern Mexico connecting the Gulf of Mexico to the Pacific Ocean. The northern half holds dense tropical forest, while the southern part features drier, open terrain.
Hernán Cortés established a transport route here in the 16th century linking the two oceans, long before the Panama Canal was built. The route was later used by merchants moving goods faster than sailing around Cape Horn.
Zapotec speakers here wear embroidered blouses and heavy jewelry on market days, continuing patterns passed down through families. Women run the stalls and speak directly with strangers without a male relative present.
The railway line between Coatzacoalcos on the Gulf side and Salina Cruz on the Pacific runs through the entire length of the area, offering views of farmland and forest. Travelers can stop in several towns along the route to visit local markets.
The Selva Zoque in the northern section is considered the largest remaining rainforest in Mexico, home to jaguars and tapirs. The dense trees and steep valleys make this stretch difficult for walkers to reach without a guide.
