When you leave Barcelona [heading to Tarragonna] on the C31 Road, do not join the C32 Motorway, the part with the mindbogglingly expansive tunnels, keep on the C32 to Sitges, great winding scenic coast road, takes just a few minutes longer, join the C32 Motorway as you get to Sitges, miss the big Tolls, very easy to do... the sea is in the way, so you cant really get it wrong....


For those who have not yet found it, the free A7 is now running from Vandellos all the way up to Tarragonna, free, empty.... more exits, much easier to get to the commercial center in Tarragonna, you come off the turn at Boavista. The A7 is the toll free replacement to the AP7. Watch the signs, some places you need to get onto the separate side lane a while before the turn.
