San Isidro, former colonial town where the wealthiest porteños had their weekend homes in the late nineteenth and early twentieth centuries, is situated half an hour to the north of Buenos Aires. On our way there, we will be able to see the Rio de la Plata (the widest in the world) and, from a picturesque pier where local fishers gather daily, appreciate a nice view of Buenos Aires to the right, and of the islands of Tigre delta to the left: a strategic spot from where to take memorable pictures. Once in San Isidro, we will walk along the main square, visit the neo-gothic cathedral and get through the many cobblestone streets to appreciate colonial buildings still inhabited by wealthy neighbors. We will go on to Villa Ocampo, summer residence built in 1891 where feminist writer and publisher Victoria Ocampo used to host prestigious figures such as novelists Albert Camus and Henry Graham Greene, composer Igor Stravinsky, and poets Rabindranath Tagore, Federico García Lorca and Pablo Neruda. The house was declared UNESCO World Heritage in 1997. After the guided visit, we may have lunch there or in some other nice restaurant by the river.
