Coming to Sitges by car is even easier. The fastest way (and the most expensive) is taking the C-32 "Pau Casals" highway (formerly A16). If you do not want to pay the toll, take road C-31 (formerly C-246. Also Known as "Costes del Garraf"). This later road is very winded. There is another highway that will also take you to Sitges, the A-7.
