Barcelona in late September is a city in celebration mode — but also, surprisingly, in relaxation mode. The streets buzz with La Mercè Festival, the city’s largest annual event, while the beaches welcome early-morning wanderers to calm sands and gentle waves. If you’ve ever wanted to mix high-energy parades with peaceful Mediterranean mornings, this is the time to visit.

Festival Highlights: La Mercè’s Energy in Full Swing
La Mercè, held every year around 24 September, is Barcelona’s official party for its patron saint, Our Lady of Mercy. The entire city transforms into a playground of tradition, art, and performance.
1. Correfoc (Fire Runs)
At night, costumed devils and dragons flood the streets, spitting sparks in a spectacle known as correfoc. Locals wear protective clothing and join the parade, dancing under showers of light. It’s thrilling, loud, and not for the faint of heart — but unforgettable.
2. Human Towers (Castells)
Daytime brings the jaw-dropping castells, human towers that rise several stories high. Teams from across Catalonia compete, their precision and strength drawing huge crowds.
3. Free Concerts & Light Shows
Plaza de Catalunya, Parc de la Ciutadella, and other public squares become open-air concert stages. Expect everything from Catalan folk music to international pop acts, often ending with piromusical, a fireworks display synced to music.

Early Morning Beach Escapes
The beauty of visiting Barcelona in September is that you can still enjoy the beach without the peak-summer chaos. Wake early and you’ll find soft golden light, warm but not scorching temperatures, and enough space to stretch out.
Nova Icaria
Located near Port Olímpic, Nova Icaria is known for its calm waters and wide sandy stretch. It’s ideal for a quick swim before festival crowds build up in the city.
Bogatell Beach
Popular with locals, Bogatell is cleaner and less touristy than Barceloneta. Early mornings here feel like your own private coastline.
Pro tip: grab a takeaway coffee from a nearby café, sit by the water, and watch paddleboarders and early joggers pass by.
Beach Days, Zero Roaming Fees
Stay online without surprise costs.
Where Locals Eat Between Events?
La Mercè is an all-day affair, so you’ll want to eat like a local — often, and well.
- Can Paixano (La Xampanyeria) – A lively cava bar near Barceloneta serving sparkling wine and hearty sandwiches.
- El Xampanyet – Tapas heaven in El Born, known for anchovies and jamón.
- Mercat de Sant Antoni – A market packed with fresh produce, charcuterie, and pastries — perfect for a quick picnic.
Avoid eating in the busiest festival squares; side streets are where you’ll find better prices and more authentic flavours.
