Chapultepec Reforma includes a tremendous variety of museums and institutions that are not formally administered by the Bosque de Chapultepec.
While Chapultepec is essentially divided into Sections, 1 - 4, the park along the avenue contains some of the most world-class sites in Mexico City. The Parque Tamayo, and the Parque Ghandi are just two examples of open public spaces. There are others.
Section 3 of the park is big nature reserve. Section 4 is still in development.
