Translation of pestle in German

My family is doing well except for my youngest daughter. She is a little ill and needs to visit many doctors. She has had several infections lately, but nothing dangerous, so we are not too worried.
Anyway, the entire bus ride lasted four hours and we finally arrived at the city of Halong. We were supposed to take a two day luxury boat tour on a ship called The Lagoon Explorer.
At around 6pm. we were back at the Chilean border and we were happy to change cars (to the mini bus again) and seeing a paved road. It took us another hour to get back to our hotel.
