Running in the Reserva Ecologica Costanera Sur is the most bucolic, off road opportunity in the central part of Buenos Aires. The Reserva was developed as a waterfront destination in 1918, and after some years of deterioration was expanded and improved upon by filling it in with debris from road construction and making it a park. Today, it is a favorite among naturalists, joggers, students, and bird-watchers. The nearly 900 acre area is home to 300 species of birds, 23 species of reptiles, 10 species of mammals, 9 species of amphibians and more than 50 types of butterflies.
A loop around the wide, wood-chipped perimeter paths is about 8 km (5 miles), with another 2 km of interior paths. There are some water and skyline views, but there are also sections where the vegetation banks are quite high. The most scenic spot is the open view across the River Plate towards Uruguay.
Note: The reserve is open every day except Monday, from 8am to 6pm. Guided tours are offered at 10.30am and 3.30pm on Saturdays and Sundays.
