Popocatepetl is an active volcano located in central Mexico, in the states of Puebla and Morelos. It is located about 70 km southeast of Mexico City and is one of the most well-known and monitored volcanoes in Mexico. The name "Popocatepetl" is derived from the Aztec language and means "Smoking Mountain".

Popocatepetl has a height of 5,452 meters (17,887 feet) and has been active for thousands of years. The volcano has a large crater at its summit, which is about 800 meters (2,600 feet) in diameter and 300 meters (984 feet) deep. The last major eruption of Popocatepetl occurred in 2000, and since then the volcano has been continuously monitored by the Mexican government and scientists due to its proximity to the heavily populated Mexico City.

Visitors to Popocatepetl can hike to the crater rim, but it is advised to take caution as the volcano is still active and dangerous. In addition to its geological significance, Popocatepetl is also considered to be a sacred site by the indigenous peoples of Mexico and holds great cultural and historical significance.
