I have visited ‘Estadio Monumental de Nunez” in December 2011. It is not very near the center of town (if you are a good walker, you can try walk there, we took a taxi), is located in the district of Belgrano. From the center of town, we took a taxi that costed around 10 US$. When you arrive there, you can visit only the Museum of the Stadium (45 pesos, about 10 US$) or pay 55 pesos and have access to Museum AND the guided tour to Stadium, which were our choice. If you are a fan of football, this stadium is a must, it was were took place the final match of 1978 Football World Cup. The Museum is nice and modern, telling the story of River Plate, his idols, photographs, uniforms, trophys and so on… The guided tour (round 45 minutes, beginning at full hours) is OK you have access to special places of the stadium, the guide tell you numbers and the history of stadium, and at the end you can go inside the field (but not walk or run on it), and take photos of the stadium. The guided tour is informative, but could be better, with some interesting facts and histories that happened there. Overall, a good experience. In your way out, you can go to a sports shop (not particularly good, the same sports shop you have in all town). Tip: it can be a little hard to get a taxi in front of stadium: you can wait there for several minutes or, what we did, walk some 6 blocks in a pleasant neighborhood until ‘Avenida del Libertador’, which is full of taxis (tip: several of them do not accept other currencies than ‘pesos argentinos’, so we had try 5 taxis until one accepted US$ as payment).
