Translation of cluck in German

At the end of October my family will be taking a short vacation to Biron Bay north of Sidney. My wife wants to visit the coast. There are many good restaurants near Brion Bay with fresh seafood.
Anyway, back on the boat station we tipped the father and left. The bus was already waiting although we were the first ones to arrive. We had to wait nearly one hour until everybody was back.
The hill was not close to the village and we did not have a lot of water with us, so that we were happy when a Brazilian couple took us closer in their rented Jeep. We walked a little further.
