We took a local blue bus from the terminal to the bottom of la rambla for a few euros, then got the metro to the Sigrada familia which was fantastic. We then took the metro back to catalunya square and walked down la rambla back to the bus stop.
Very scruffy around docks and no tourist signage anywhere even in the city centre - difficult for an independent traveller. Interesting to see the boat sail under the 25th of April bridge with just 5m of clearance.
