Last August, I simply took the airport bus shuttle into Barecelona Centro, a taxi to the bus station (I asked him to go to "Estation de Autobuses a Pamplona") and bought the ticket direct (54 Euros). On the bus, you will be given (included in price) water, nuts, and biscuits.
I landed in Barcelona at 13.10, was on the bus to Pamplona at 15.15. Arrived in Pamplona 20.30, found the Albergue municipal, bought a pilgrim passport (credential), got a bed there, got me some late evening food (albergue closes at
22.00), and started walking next morning
(My original armchair plan was to go back to Roncesvalles/SJPdP by bus/taxi, but once in Pamplona, I just wanted to start walking towards Santiago: Kind of loose plans I had; but it all worked out nicely: That's the beauty of not overplanning/buying lots of tickets in advance: Change of plans means money lost).
The
ONLY trouble I had was my bed neighbor in the Albergue in Pamplona: She (very young) started text messaging with some friend(s) at 3.20 in the morning (night!) and continued until I got up... Next day I bought earplugs at the first pharmacia I spotted :lol:
