The best thing to do in Buenos Aires is to walk! The city is made of wide avenues, grid shaped streets, parks, cafés, and it is an endless walking route. Especially at spring time like now at end October, the jacaranda trees with their purple flowers make your head rise to the sky while your feet follow your instincts to get to another corner of this beautiful city. A one and a half kilometre route between San Martin Square and Lavalle Square: at the end of the famous pedestrian street of Florida you reach to the park of San Martin, as you take the park on your behind and head to the main avenue of Carlos Pellegrini you arrive at the traffic lights, try to cross the twenty line avenue made of Carlos Pellegrini and 9th of July at once, it is not possible unless you are running. Actually it is the widest avenue of the city with four traffic lights, twenty lines and a separate one for public transportation in the middle. As you cross you will reach to the Colon Theatre which is the biggest opera house of the country. Actually it is cited among the top five opera houses in the world in terms of acoustic quality. You can make guided tours inside the theatre, check the programme. You then take the first street to the right and continue walking, see the famous obelisk behind and then reach to another square, which is the Lavalle Square. This green square behind the Colon Theatre is where the Ministry of Justice is located. It is also important for Jewish minority and there’s a synagogue and a Jewish Museum here (another important minority in Buenos Aires is the Armenians- the biggest community after Armenia- and most of them live in Palermo). I am taking the road towards West to reach to Sarmiento Street and arrive at the San Martin Cultural Center, one of the cultural centres with free activities as there are many here in Buenos Aires.
