About 40km south of Barcelona and easily accessible by train, Sitges is somewhere to go for a day at the beach, or for its nightlife.
For the next ten days it's also home to the Sitges Film Festival, now in its 40th edition. If you like your films to have titles like The Devil's Chair, I'm a Cyborg But That's OK (aka Saibogujiman Gwenchana), Sukiyaki Western Django, Confession of Pain, The City of Violence, American Zombie and Los Totenwackers (etc.), you'll just love this.
If not, the beach is right down that way…!
