Despite Xochimilco’s Unesco World Heritage status, encroaching urbanization and illegal settlement along the canals continue to strain this unique habitat. At least one endemic species of the zone, the axolotl (a fishlike salamander) is in danger of extinction. Thus in 1991 the Ecological Park of Xochimilco was established, about 3km northeast of downtown Xochimilco, both to recover the fragile ecosystem and to provide a retreat for stressed-out urbanites. Covering some 2 sq km, the protected area comprises a botanical garden and artificial lakes, home to a variety of waterbirds. Stroll the pleasant pathways, or rent a bicycle or a pedal boat for more extensive exploration. In the park’s southeast corner, chinampas have been set aside to demonstrate traditional indigenous cultivation techniques. A visitors center has displays on plants and birds. Trajineras departing from Embarcadero Cuemanco, 2km west of the park entrance, ply this lower-key section of the canals. To reach Parque Ecológico de Xochimilco, take the Tren Ligero to the Periférico station. Exit on the Xochimilco-bound side, then go through the tunnel that underpasses the Periférico freeway. Emerging from the tunnel, turn right and walk to where you catch a ‘Cuemanco’ pesero; the park entrance is a 10-minute ride.
