After being allowed to leave Chile (see post below) we left for Mendoza, Argentina by bus. Even though we were told about the quality of the buses in this part of the world I was still surprised by what we got for our money. For $40 dollars each we had ourselves a Semi Calma (semi -bed) bus with food provided.
This took as on an incredible 8 hour journey through the Andes to our destination of Mendoza. The views were incredible and I can safely say that this was one of the best road journeys I had ever experienced. If you are ever in this part of the world I would highly recommend it.
