On the way to the border, our guide distributed the necessary paperwork among us and advised us on how to fill them out. He also repeated what should we expect and what would happen several times. After arriving at the border he recommended an exchange office and then introduced his colleague, who would be our guide after we crossed over to Bolivia. Then we all went to the Peruvian customs and we all got an exit stamp. When everyone from the bus legally left Peru, we crossed the border on foot. A bus was already waiting for us there. The Bolivian custom office was next, where some of us had to arrange for a visa, but our guide assisted them. Only after everyone has crossed the border successfully did our bus set out for the nearby town of Copacabana.
