The River Boat Ride boasts a long 400-year history, with poles piercing holes 10 centimeters deep into the river walls every day during those long years.
For instance, you can see some of those holes around here. Pay attention to where the ferryman dips the pole so you don’t miss it. Poles and other tools are made by the ferrymen themselves, just like in the past, as the ideal shape for the pole depends on the age and physique of the ferryman. The riverbed is covered in rocky gravel and sand, so poles do sometimes get stuck. It takes a few years to learn the tricks of the ferryman trade.
