Iztaccíhuatl–Popocatépetl National Park, National park between State of Mexico, Puebla, and Morelos, Mexico.

Iztaccíhuatl–Popocatépetl National Park stretches across three Mexican states and encompasses two of the country's highest peaks, including one active volcano. The terrain ranges from forested lower slopes to snow-capped summits, with trails passing through different climate zones and crossing varied types of vegetation.

President Lázaro Cárdenas created this protected area in November 1935 to safeguard both volcanoes and their surroundings from further deforestation. The establishment was part of a larger initiative to create natural reserves that spanned several regions of Mexico.

Popocatépetl takes its name from Nahuatl popoca, "to smoke", and tepetl, "hill or mountain", giving "smoking hill"; Iztaccíhuatl combines iztac, "white", and cíhuatl, "woman", meaning "white woman". Both names predate the Spanish conquest. Indigenous cultures of Mexico regard the two volcanoes as living beings with a divine and heroic past, and their birth inspired legends such as the idyll of the volcanoes.

Mountain streams within the reserve flow downhill and contribute to the water supply of several major cities through natural filtration. Visitors should watch for signage about volcanic activity, as certain zones may close when risk levels rise.

The endangered volcano rabbit, called teporingo in Mexico, lives in the high-elevation grasslands of Iztaccíhuatl and Popocatépetl and only three other central Mexican volcanic peaks. It is among the 48 wild mammal species recorded in the park, which also counts 161 bird species, three-quarters of them resident.
