Tarragona is the first large seaside town south of Barcelona. The town also offers a number of historical sites including churches from several different periods and a well preserved Roman colosseum. The town itself has the usual Spanish assortment of plazas sprinkled with cafes and tapas bars. Tarragona is a good choice if you only have a day or two to get out of Barcelona, otherwise the beaches further south or the remoter seaside villages to the north of Barcelona offer a more unique experience.
