Wow these are some terrible pictures.
Wow most of these look deplorable. Not sure if it’s a real article or a joke. Anyway, you should have included Mexico City’s Chapultepec Central Park (also known as Chapultepec Forest, since it’s so huge). It’s massive (1700 acres), and even has several museums and archeological sites to visit, as well as a zoo and a pre colonial castle. All of this right in the middle of the most heavily populated city in Mexico, and free for everyone to visit and walk and do park-ly related things.
