I am walking the Camino in June and flying into Barcelona from Australia. I am actually starting the walk from Pamplona and will need to return to Barcelona to continue a holiday on to New York after the Camino. This being the case I will be flying over to Spain with a suitcase as well as my small walking pack. I have looked at luggage storage at the airport but it is up to 5 euro per day, which considering the walk will be 4 weeks (give or take) that will cost quite alot. Does anyone know where I can leave a suitcase for a month without costing me a ridiculous amount of money? :?
