Have just booked into Hostal Remigio in Tudela with a view to taking the train to Pamplona for one day and Zaragoza the next, instead of the stress of driving in. Can anyone confirm that this makes sense ie. that you can board a train at Tudela. Remigio says it's 10 mins walking distance the the station but no reviews mention it. Also when I arrive in the cities is the town train station easy walk to the old centres?
