When we got to Roscoff we had not intended to stay there for the night. We actually had not quite figured out, yet, where we wanted to stay, so we broke out the maps and started planning. While doing so we enjoyed the view of a very unusual harbour. Despite the fact that the high tide was coming in again already the water level was so low that the entire harbour was dry. People were walking around big ships and smaller boats on the ground of the harbour.
We watched the water come back while deciding to stay and booked a hotel online that was just on the other side of downtown.
