As much of the borough is still classified as an ecological reserve, there are a number of green areas open to the public. These include several “forests” such as the Bosque de Nativitas, the Xochimilco Ecological Reserve, the Centro Acuexcomatl, and Michmani Ecotourism Park. There are several parks designated as forests such as the Bosque de Nativitas and the Bosque de San Luis Tlaxialtemaco. These are considered “areas of environmental value” by the city and established to counter some of the damage caused by urban sprawl in Xochimilco. These areas are open to the public but with minimal services such as picnic tables and horseback riding. The largest ecological area is the Xochimilco Ecological Reserve, inaugurated in 1993. It covers over 200 hectares and is filled with numerous plant and animal species that live or migrate here. The park also contains a bike path, thirty five athletic fields, a flower market and a visitor center. It is second in size only to Chapultepec Park. It is also possible to travel in some of the canals here by trajinera. The Centro de Educación Ambiental Acuexcomatl (Acuexcomatl Environmental Education Center) is located on the road between Xochimilco center and Tulyehualco. It contains fish farms, beekeeping, plant nurseries and greenhouses as well as sports facilities, classrooms, workshops, an auditorium, an open-air theatre and a cafeteria. It is in Colonia Quirino Mendoza. Michmani is an ecotourism program sponsored by the borough, which is situated on fifty hectares of chinampas. The site offers kayaking, recreational fishing, a temazcal, cabin rentals and environmental education.
