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.
In the afternoon we went to the Cerro Catedral which is a small mountain not far (30 minutes) from the city. You can either climb up or take the chair lift. We chose the second option.
