Spanning from Retiro to Tigre, Av. Libertador is one of the main thoroughfares of Buenos Aires. It is also one of the more upscale Avenues in the city, and has much fewer bus lines than other avenues in BA. It is 30 km. long and is named after San Martín. From its most southern tip in Retiro to where it ends up north, here is what you will find on this emblematic avenue.
The famous Recoleta Plaza Francia Park borders with this Avenue and has a great artisans fair. On the opposite hand is the Buenos Aires Fine Arts Museum. Also along this avenue is the stunning Museo de Arte Decorativo.
Continuing up the park lined Avenue, upon reaching Palermo, we will find the famous Monument to the Magna Carta and the Four Regions of Argentina (more commonly known as Monumento a los Españoles). At this intersection we also have the old BA Zoo, now an ecopark, on one corner, and the entrance to the renowned rose garden (Rosedal) on the other. A little further up the road we will find the Palermo horse tracks before getting to Belgrano.
In Nuñez, right at the border between the capital and the suburbs, is Memorial Museum and Haroldo Conti cultural center, both which used to be a detention center during the military coup. It is a relevant historical spot with a exhibits and a lot of artistic programs aimed at bringing awareness to human rights issues.

Finally, the avenue ends in the Tigre delta which is worthwhile exploring on a boat. You can find a list of suggested tours here.
