Six Flags México is a amusement park located in the Tlalpan forest and borough, on the southern edge of Mexico City, Mexico. It is owned and operated by Six Flags, and is the most visited theme park in Latin America with 2.8 million annual visitors. It was previously known as Reino Aventura when it was Mexican-owned and featured the orca whale Keiko as its principal attraction.

Tlalpan is a borough in Mexico City. It is the largest borough, with over eighty percent under conservation as forest and other ecologically sensitive area. The rest, almost all of it on the northern edge, has been urban since the mid-20th century. When it was created in 1928, it was named after the most important settlement of the area, Tlalpan, which is referred to as “Tlalpan center” to distinguish it from the borough.
