The Sitges Film Festival, running for ten days every October, has been the major international event on the genre-cinema calendar since 1968. It draws thousands of fans and industry professionals, sells out hotels for months in advance, and gives the otherwise summer-oriented town its most concentrated cultural week of the year.
Films screen at the Auditori Meliá Hotel and several smaller venues in and around the centre. Tickets and accreditations sell quickly; check sitgesfilmfestival.com for programme and dates. Even if you're not attending screenings, the town in festival week is worth visiting for the atmosphere alone.
