Six Flags México is Mexico City’s biggest amusement park. The first Six Flags park to open outside the United States, it was instantly the biggest in Latin America.
The park originally opened in 1982 as Reino Aventura. Premier Parks took over in 1999 and the park reopened under the Six Flags marquee in 2000. The new name came with a greatly enhanced range of rides and attractions.
Both Capital Bus and TuriBus run regular excursions to the park. For international visitors in the north of the City these can be very convenient. Check their websites, or you can ask on the bus.
