Translation of khakifarben

There we saw a lot of these beautiful trees which I had heard about when I was back in Germany. We visited the folliage and saw some amazing lakes in the northern part of the state, different from the rest.
How could I get better in Spanish if I had to eat by myself. Impossible. The next days we always ate together and sat around the table for hours discussing politics and the lives we were living.
We spent the entire day doing nothing, just waiting for the night train which would take us into the northern mountain area of Vietnam, close to the Chinese border. The train left at around ten.
