Barcelona is a city that is worth visiting. So you can take advantage of the conference and visit Barcelona before or after the conference days.
Barcelona is only one hour away from Tarragona, so if you arrive in the Barcelona Airport, and you have decided to visit Barcelona before the conference, you can stay in Barcelona a few days and then take a bus to Tarragona on Sunday, September 18th. In that case we recommend you to arrive at least on Friday or early on Saturday morning before the conference week, having enough time to visit the spectacular Sagrada Família, and maybe the Casa Batlló and La Pedrera. You can also have a walk through the Gothic and Les Rambles or perhaps you would like to enjoy the city on a Turistic Bus. There are many possibilities to enjoy in Barcelona, and as the dates of the conference get closer, we will give you more information for your Barcelona visit.
