Overview:
Sitges is a great day trip for anyone in BCN. It's about a 40 min ride from Barcelona. It's a cute french town with a beautiful beach and cathedral. It feels like a whole different experience than Barcelona, even though it's not that far away.

You can take the Rodalies (Orange Line at the same metro stop we use to get to school). You first take either R1, R3, or R4 in the South direction to Catalunya. Then you switch to the R2 toward ?? at Platform 8 & 9.

All total, the round trip cost is $7.60
Suggestions:
This is a one day trip, so leave in the late morning and you can be back by evening.
