Here are some pics from the border of Peru and Bolivia. The bus stops, everyone gets out, then you get your exit stamp for Peru. Then you change your money cos everyone says to do it there, and they give you the worst exchange rate ever. They don´t tell you that if you wait until you are in Copacabana, the exchange rate will be much better. Then you walk to the arch you see in the one pic, and you are in Bolivia, and you get your passport entry stamp there. Then you get back on the bus. Takes about half an hour for everyone to go through the process.
