Teuhtli volcano

Teuhtli is a volcanic cone on the southern edge of the Mexico City basin and is one of the many volcanic features that make up the Chichinautzin volcanic field. It is a noticeable hill in the city’s southern highlands.

The volcano presents forested slopes and natural terrain typical of the outer ring of cones around the valley, and it is visited by people interested in geology, hiking and local nature. Trails and informal routes lead up parts of the cone where access is permitted.

Teuhtli formed as part of the region’s volcanic activity in the Pleistocene-Holocene period and is one of a cluster of monogenetic cones and lava flows that define the Chichinautzin field. The volcanic landscape around Mexico City developed over tens of thousands of years through repeated strombolian and effusive eruptions.

The cone stands on the southern flank of the Valley of Mexico, on the higher ground that borders Mexico City to the south-southwest, within the greater metropolitan area.

• Volcanic context: Part of the Chichinautzin volcanic field on the southern edge of the Valley of Mexico, forming one of the many volcanic cones surrounding Mexico City.

From central Mexico City, take Metro Line 2 to Tasqueña and transfer to the light rail (Tren Ligero) to Tláhuac; from Tláhuac station a taxi or local colectivo will cover the 10-20 minute ride toward Cerro Teuhtli. By car, head southeast on Calzada de Tlalpan and follow signs to Tláhuac; parking is informal near the foot of the hill.

• Start from the south side (Tláhuac) to avoid the steepest paved service road; the walk from Metro Tláhuac is about 6-8 km and follows quieter streets.
• Bring a rain jacket during summer (May-October) - the clay paths turn to slick mud quickly.
• Most visitors come at dawn or late afternoon for light and city views; avoid midday for heat and pollution haze.
