After crossing the Río de la Plata, I arrived in the argentinian capital city. Buenos Aires is a large city with many different neighbourhoods to see, and even natural areas in the city. There are other charming towns close to it, like Tigre for example.
After having spent one month in Buenos Aires, I resumed my way to the south. Following a recommendation for its amazing landscapes, I went to Sierra de la Ventana. Indeed, it is very different from the city. The village is surrounded by yellow hills due to dry grass in summer. It is much greener in winter.
We are in the gate of Argentinian Patagonia. Carmen de Patagones is in the south of the province of Buenos Aires, and Viedma, in the north of the province of Río Negro, the most northern province of the east coast of Patagonia. The Río Negro river is the natural border between both towns and both provinces.
Because of the lack of cheap accommodation, people travelling on a budget can't stay too long. Fortunately, the towns are small enough and you don't need to stay longer.
Las Grutas is a town next to the Ocean. The beaches are it's main appeal. It will please the vacacioners looking for idleness in the sun. However, the small budgets won't stay too much. The accomodation isn't very cheap...
Puerto Madryn is a beautiful village on the side of the ocean. The prices are much more affordables than in Las Grutas.
Even if the village itself has beautiful places to visit, its interest is more outside. You can watch the wales in the Valdés Peninsula (Unfortunately, I wasn't there in the right time) and the Punta Tombo National Park is crowded by penguins.
