Which BUS do we take from the PAMPLONA train station to the OLD CITY??

Many of you have been asking a very commonly asked question:  From the train station, which public bus is best for transport to the old city, Pamplona?  The only busline from the RENFE train station in Pamplona, to the old city, where the sanfermines take place, is the Bus # 9.....You will see the bus-stop just outside the main entrance/exit of the train station....and, you can expect a short 10-15 minute bus trip into the old city, depending on San Fermín traffic!
