C31 is a Busy Coastal Road with Sharp Curves and Stunning Views in Barcelona

# C31: Catalonia's Coastal Thrill Ride

Ready for a scenic drive that'll get your heart pumping? The C31, affectionately known as Costes del Garraf, is a stunning coastal corniche hugging Spain's Catalonia shoreline southwest of Barcelona. Fair warning though—if hairpin turns make you queasy, you might want to sit this one out.

This charming road has serious history. Originally paved at the end of the 19th century over a medieval route, it's evolved into a beloved (if chaotic) coastal drive that stretches from El Vendrell to Castelldefels, running practically alongside the Mediterranean. But here's where it gets wild: the real action happens in that intense 16.5 km stretch between Castelldefels and Sitges, where you'll navigate a jaw-dropping 86 curves as the road clings to the cliffs of Parc Natural del Garraf.

The route is fully paved but incredibly narrow—one lane in each direction—and perpetually packed with cars. Picture yourself threading through tight bends with the ocean sprawling below, your brakes working overtime as you wind along these dramatic clifftop curves. Overtaking? Forget about it. The road offers nowhere to pass, and weekend traffic gets absolutely mental.

What you do get are absolutely breathtaking ocean vistas and several pullout spots to snap photos. Just expect company—especially on weekends and holidays when tourists flood in, plus weekday cement trucks rumbling through. No shoulders, tight curves, hot brakes, and zero escape routes make this one of those drives you'll either absolutely love or absolutely dread. Sitges, a charming coastal town at the end, was actually a tourism pioneer in both Catalonia and Europe—so at least you'll have a rewarding destination after conquering this coastal beast.
