The beauty of Palermo: Although Palermo is not the largest green space in Buenos Aires (the Parque de la Ciudad is far larger) it is the most beautiful area of the city. The most exclusive apartment buildings in Buenos Aires are along Avenida Libertador, facing this huge green space, that is probably a mile and a half long, between Avenida del Libertador and the local metropolitan airport (Aeroparque). Here is a map of the complete area (marked in green): www.bue.gov.ar/recorridos/?menu_id=137&info=auto_contenido. There are many attractions in this area, starting by the Botanical Garden, an incredibly beautiful area located between avenues Cabildo and Las Heras. In a surface of some 20 acres, the Botanical garden has some 5,500 different classes of trees and plants and some 33 very nice sculptures and monuments. It was inaugurated in 1898, more than a century ago. It has a Roman garden (Century 1 A.D. vegetation), a French garden (Centuries 17 and 18 vegetation) and an Oriental garden. This is the website of the Botanical Garden: www.buenosaires.gov.ar/areas/med_ambiente/botanico/?menu_id=11360. The zoo is the most important one in all Argentina, and is just across the road from the Botanical Garden. It has 89 kinds of mammals, 49 kinds of reptiles and 175 kinds of birds, with a total population of 2,500 animals. It was inaugurated in 1875 by President Sarmiento. This is its official site: www.zoobuenosaires.com.ar/index_fla_on_popup.htm.
Beyond the zoo and just across avenue Figueroa Alcorta you will find the Planetarium, that offers fantastic virtual tours to the universe. I was amazed at the quality of the show, and the admission fee is very low. This is their site: www.planetario.gov.ar. Click on the yellow links in the center of this page. The Japanese garden is another place that you will thoroughly enjoy. Years ago, I have taken some beautiful films in this area. The Rose Garden (more than 12,000 rose plants), the lake, where you can rent a boat and do some rowing, the Palermo horse racing track (created in 1876), renown in the whole world, and the Argentine Polo field are other interesting places you can visit while you are in this area. To make it simple, polo is a sort of hockey game, but riding horses. The monument to Spaniards and the Persian Column complete the picture of Palermo, that also has a golf course and a number of clubs in the area. The Sociedad Rural (Farmers Society) is the most important exposition center in all Argentina. It is just facing the Plaza Italia subway station, in front of the Botanical Garden. If you have visited Buenos Aires and have not gone to Palermo, you do not have a complete picture of the city.
Costanera Norte: The Northern coastal avenue along the River Plate and beyond the local metropolitan airport. It is a very pleasant area, and there are many restaurants where you can enjoy a barbecue. Most of these restaurants are between an artificial lagoon and the River Plate.
River Plate Stadium. One of the two most important soccer clubs in Buenos Aires. Just beyond the "Costanera Norte".
Colon Theater. If you are fond of classical music or ballet, you cannot miss it. It is one of the most luxurious buildings in all Buenos Aires, located on the Nueve de Julio avenue. This is their website: www.teatrocolon.org.ar.
Nueve de Julio Avenue: 500 feet wide, it is the widest avenue in the whole world. Lavalle Street: Most of the movie theaters or cinemas are on this street, that also has many restaurants, including La Estancia. Corrientes Street: The street of the Theaters (Gran Rex, Opera, Metropolitan, and many others. Boca: The home of Boca Juniors and its stadium, it also has many pizzerias, the famous Caminito area, where you can take fantastic photos, and the Riachuelo. I suggest visiting this area in a city tour. San Telmo. Known for its restaurants and tango shows. Costanera Sur: The most important ecological reserve in the city of Buenos Aires, along the southern portion of the coastal avenue. Puerto Madero: Undoubtedly the most modern part of the city of Buenos Aires. Beautiful buildings, luxury hotels, excellent restaurants, all by the riverside. It is very near Retiro and behind the Sheraton hotel Have a glance at the photos, and I know you will want to go. Click here: www.corporacionpuertomadero.com.
Parque de la Costa. Very near Tigre, it is the end of the Tren de la Costa (Train of the Coast) that starts off at the Bartolomé Mitre railway station (Trains from Retiro station arrive here), or you con go on a 60 bus to get this train). It is one of the most complete mechanical attractions park in Buenos Aires. I understand it also has a casino. Have a look at their link: www.parquedelacosta.com.ar. There are many other places you can visit in Buenos Aires, but I have highlighted the most important ones. Enjoy your stay in Buenos Aires.
