Translation of prehistory in German

We decided to fly directly to Hanoi and booked a flight for the same day. Before we left we still had some time to visit the War Remnants Museum. One could see the former headquarters of the South.
We cursed our bus driver and tour guide and everybody knew that these people were not professional. After 2 hours we arrived at the destination. It was a little boat station on a riverbank.
We woke up very early because we wanted to continue to Bariloche in Argentina. We bought some food and sat down by the lake to eat a breakfast sandwich. It was so foggy that we could not see the volcano.
