La Merce 2026 in Barcelona: Correfoc, Castells and Fireworks

Passeig de Gràcia, Saturday 26 September

The correfoc, literally « fire-run », is a parade where diables dressed as demons and fantastical beasts (dragons, mules, bulls) spin flamethrowers and showers of sparks through the crowd. It’s anything but a spectator sport: according to the Barcelona City Council, the tradition draws on the Ball de Diables, documented as early as the 12th century, but today’s highly pyrotechnic version dates from the 1970s: the word « correfoc » first appeared in 1977 at the Festa Major del Clot, and the first official La Mercè correfoc was staged in 1978 by the theatre collective Comediants.

Since 2022, the route has moved from the historic Via Laietana to Passeig de Gràcia, covering around 600 metres between Carrer de Provença and Carrer del Consell de Cent. In 2026, two sessions run back-to-back on Saturday 26 September: a gentler kids’ version at 6pm and a considerably more intense adult version at 8.30pm. According to Catalan News, more than 80,000 spectators had already packed Passeig de Gràcia by 8.30pm in 2025.

Highlights

• New for 2026: the Porta de l’Infern, a 4 × 8 metre structure that kicks off the show
• A dedicated kids’ version at 6pm, designed to ease younger visitors in before the adult show’s intensity
• Punts lila (purple points, for reporting sexist and LGBTI-phobic behaviour) are set up along the route

Park Güell is actually hosting a special show on 24 and 26 September as part of Gaudí Year 2026 and the park’s centenary. A skip-the-line guided tour lets you dodge the queue and enjoy the site without eating into your La Mercè schedule.

Plaça de Sant Jaume, Thursday 24 September

Castells are human towers built by amateur teams called colles, stacked level by level (usually 6 to 10 tiers): the sturdiest members form the base, while the lightest, often children, climb to the top. The enxaneta, typically a very young child, crowns the tower and raises an arm to signal success, met with total silence followed by applause. According to UNESCO, this knowledge was inscribed on the Representative List of the Intangible Cultural Heritage of Humanity on 16 November 2010; it’s passed down purely through practice, generation after generation within each colla.

Barcelona has six active colles: Castellers de Barcelona (1969, red shirts), Castellers de Sants (1993, grey), Castellers de la Vila de Gràcia (1997), Castellers del Poble Sec (1999), Castellers de la Sagrada Família (2002) and Colla Jove de Barcelona (2010). The diada castellera de la Mercè, which brings all of these colles together on Plaça de Sant Jaume, takes place on Thursday 24 September, a public holiday in the city in honour of its patron saint, according to the official programme from the City Council.

Highlights

• All six Barcelona colles build their towers in front of the town hall and the Generalitat palace
• The Pla de la Generalitat side offers one of the best viewing angles
• The tallest, most spectacular attempts are usually saved for later in the day

Bogatell Beach, Sunday 27 September, 10pm

The piromusical is the fireworks show synchronised to music that closes every La Mercè. Big change for 2026: because of building works at Fira de Montjuïc, the show is leaving Avinguda Maria Cristina, its historic site by the Font Màgica, for Bogatell Beach. The move is confirmed by six independent sources, including Catalan News and 3Cat. In 2025, more than 110,000 people gathered on Avinguda Maria Cristina for the show at its historic site.

The 2026 soundtrack is by Josep Montero, singer with Catalan band Oques Grasses, chosen after the controversies of 2024 (soundtrack by Rosalía) and 2025 (Estopa), both criticised for featuring too few songs in Catalan. According to VilaWeb, Montero has deliberately built a Catalan-heavy programme for this edition.

Highlights

• By metro: line L4, Bogatell or Llacuna/Poblenou stations
• You can watch from anywhere along the seafront, not just the beach itself
• Nearby bus routes: 6, 36, 41, 92, 141

El Born, Eixample or Barri Gòtic

Accommodation prices climb noticeably during La Mercè week, especially in Barri Gòtic and El Born. Book at least three to four weeks ahead, more if you want to be in the centre. El Born strikes the best balance between atmosphere and price, Eixample has the most convenient transport links for a first trip, and Barri Gòtic offers a more atmospheric — if noisier at night — medieval feel, with no metro station inside the neighbourhood itself. For softer prices, the Maresme coast (Calella, Santa Susanna) is 40-60 minutes away by suburban train, and Castelldefels or Sitges around half an hour.

A Barcelona trip budget also needs to factor in the 2026 tourist tax, charged per night on top of your accommodation and slightly higher in the city centre. If you’d rather start from a ready-made framework than piece every step together yourself, a 5-day Barcelona itinerary can be adapted around the La Mercè dates.

The city centre is very walkable. Beyond that, the metro is fast and runs late throughout the festival. From El Prat airport, expect around €35-50 by taxi, €5.90 on the L9 metro line, or €4.90 on the Rodalies train. Skip the car: street closures and near-impossible parking are the norm on festival days. As for the weather, late September sees average temperatures of 24-27°C, a sea still warm enough to swim in at 24°C, and rain that tends to fall as short showers rather than sustained downpours.

Getting there from the UK is straightforward: British Airways, easyJet, Vueling, Ryanair and Wizz Air all fly direct from London to Barcelona, with a flight time of roughly 2 hours 10 minutes and dozens of departures a week — worth booking early, since September is typically one of the cheaper months on the route. One practical heads-up for 2026: since 10 April, UK arrivals into Spain go through the EU’s Entry/Exit System (EES), which records a facial scan and fingerprints at your first crossing — build in extra time at passport control, especially during busy periods. ETIAS pre-authorisation is not yet required for short trips, but it’s worth checking the latest guidance on gov.uk before you travel.
