I'm going to be spending one night in Pamplona during a road trip in August and will have a car with me. None of the accommodation I've looked at has free parking, even the places a couple of km out of the centre - they all charge at least 12 euros. Can anyone tell me if there's any cheap/free overnight parking somewhere? It doesn't have to be in the centre - we're happy to stay a little way outside the centre and walk/take a bus in. We're on a bit of a tight budget and costs are really going to rack up if we keep having to pay a lot for parking.
