Translation of nucleus in German

So we decided to move on. We were looking to get the next flight to Hoi Ann, which is located right in the center of the country, but we were told that there had been floods a week earlier.
There are many lakes situated throughout the center. The entire atmosphere here was more relaxed. Our first spot was the Ho Chi Minh mausoleum. In addition there was a small Pagoda nearby.
The road was a really horrible, but the lakes and the surrounding woods were colorful and impressive. We drove for two hours through the forest towards San Martin de los Andes, but decided to turn back before it got dark.
