coming to salou in may,used to use ryanair,but flt times and prices are now not so good,easyjet into barcelona and a shuttle seems good ,how long does it take barcelona to salou please

Hmmmm...depending upon any stops on the way, and route taken, it should take around 90 minutes. By car straight through I can do it in an hour or so, but the coaches go a bit slower
I suppose anything between 90 minutes to 2 hours would be a reasonable guess.
