Although little is said about it, the Tetlalmanche Volcano in Iztapalapa is a natural treasure waiting to be discovered within Mexico City. This imposing titan is not only a local legend but also towers over the landscape as the undisputed peak of the Sierra de Santa Catarina.
According to Mexico City, this colossus of Iztapalapa and Tláhuac is also known as Volcán Guadalupe, El Borrego, and even the curious Cerro de la Tortuga. However, its name in Nahuatl means “mountain that throws stones.”
It’s fascinating to think that this monogenetic volcano erupted just once in the distant Mesozoic Era and that, having survived intense mining activity, it still boasts its silhouette and a distinctive crater at the very top.
Elevation, Wildlife, and Hiking on the Tetlalmanche Volcano in Iztapalapa
Reaching its summit at 2,820 meters above sea level is a challenge worth every drop of sweat. Upon conquering the summit, you’ll be greeted by a spectacular view that includes the snow-capped mountain range and the beautiful lakeside landscapes of Tláhuac.
Best of all, you don’t have to go in blindly—SEDEMA and the municipal governments of Iztapalapa and Tláhuac often organize free hikes and guided tours so you can safely enjoy its trails. Be careful, though, because it’s not recommended to set out on your own, as it can be dangerous.
This entire ecosystem is sheltered within a vast protected natural area spanning 748.55 hectares. It plays a key role: it captures rainwater that nourishes and purifies the capital’s aquifers.
Exploring it means encountering wildlife, where the star of the show is the tepayatzin, or horned lizard—a reptile revered since Ancient Mexico. If you’re lucky, you’ll spot one, as they’re masters of hiding: they flatten their bodies to cast minimal shadows, and if they feel cornered, they defend themselves with the distinctive horns on their heads.
Put on your sneakers, pack plenty of water, and conquer this fascinating volcano in Mexico City!
