Estadio Olímpico Universitario
Diego Rivera friezes outside of the Pumas stadium entrances are not to be missed, and if you have extra time, walk around the UNAM campus, where you'll find a 4-sided multi-story mural by Juan O'Gorman, and some Siqueirros.
It's recommended to go to the Estadio Olímpico Universitario without wearing a kit, as you might be directed to a section with low visibility if you're spotted wearing team colors.
