Newbie help required !

Barcelona to Burgos -you can take bus, train or airplane.
Taking a bus is the cheapest and easiest way I think.
It takes quite many hours but you can follow the beautiful Spanish country side and the camino through the bus windows. The buses are quite comfortable, too.
Most buses leave from the Estacion Nord in Barcelona.
Why not taking a night bus and spend a whole day in Burgos (I love Burgos) and meet your first fellow pilgrims your first night in the excellent albergue by the cathedral or start walking right a way in the morning when you arrive and walk a short day of 10 km to Tarjodos.

I walked from Burgos to Santiago in 22 days in April 2011.
