River transportation was very fine, but getting around Basel is also very good. The trams date back to the days of horse-drawn trams, and, evidently, the rails were never abandoned and destroyed like we did in the US, rather the move was made from horses to electricity, and the tram lines extended and modernized.
Basel proper has a population of 166,000 with a combined area population over 800,000. For this size population the trams cover a wide area with a frequent schedule. We have never waited more than a few minutes at our tram stop, and the electronic board at the stop displays the number of minutes remaining until the tram arrives. Here is the tram map with all the tram routes in color:
