Jardín Botánico del IB-UNAM
On the west side of UNAM's campus, this sprawling 32-acre swatch of greenery is Mexico's oldest botanical garden. Created in 1959 to preserve and encourage the study of the nation's diverse flora that spans the tropical, high-desert, and forested mountain regions, a walk through this remarkable landscape and its many greenhouses truly showcase Mexico's incredible biodiversity. The garden consists of 15 different collections, and contains more than 1,600 specimens, with a particularly diverse and remarkable array of cacti. A critical aspect of the garden's mission is protecting endangered flora as well as developing methods for sustaining them.
