[1] Tulcingo De Valle (in Náhuatl: tolli-tzintli-co, ‘tule-pequeño-lugar’ ‘in a small space’)’ is located within the municipal state of Puebla, in the central oriental of Mexico.

To the north, Tulcingo is located close to Chila de la sal (“head ground salts of spices”); to the east, is Tecomatlan (“Pot made of Stone); towards the south is the state of Guerrero, and Oaxaca is in the west, in the municipality of Albino Zertuche.

[2] The municipality occupies a zone of dry land, which is part of the province of ancient Mixtec land, in the Sierra Madre del Sur mountains (“mother’s Farm of the South”).

The rivers form a major part of the low plane Mixtec Poblana.

Because of the rivers, agriculture thrives in the Selva baja caduciofolia.
