Sónar is one of the most important music festivals in the world, and the OFFSónar party circuit that runs simultaneously across Barcelona's clubs may actually be more exciting. The official festival is credible, forward-thinking, and impeccably programmed. The city-wide unofficial circuit that erupts around it is where you'll find the real underground energy.
What Is Sónar Festival?
Sónar 2026 runs June 18-21. The festival is split into two experiences: Sónar by Day and Sónar by Night. Sónar by Day takes place at Fira Montjuïc (accessible via Montjuïc cable car or Uber), running from noon to 10pm with a more experimental and arts-focused programme. Sónar by Night is held at Fira Gran Via (accessible by L9 metro), starting at midnight and running until 8am. It's the most complete advanced electronic music festival experience you'll find anywhere.
The programming philosophy is uncompromising: Sónar has consistently presented artists before they became mainstream. The festival's reputation is built on credibility, not commercial appeal. If you care about electronic music at any level, this festival deserves to be on your list.
What Is OFFSónar?
OFFSónar is the unofficial party circuit that erupts across Barcelona during Sónar week. It is not organized by Sónar; these are completely independent club nights that coincide with the festival. Every major promoter and club in the city runs their best event of the year during this week. The result is the most concentrated week of quality electronic music events in Barcelona, and arguably in Europe.
Key OFFSónar Venues
- Poble Espanyol: the crown jewel of OFFSónar. A magical outdoor venue on the Montjuïc hillside with cobblestone streets, baroque architecture, and multiple stages. The best setting in Barcelona for outdoor parties. Elrow, Circoloco, and other top promoters take over multiple nights here.
- Sala Apolo: the Nitsa stage runs its best OFFSónar programme during the week. La [2] also has programming. Both stages are consistently excellent.
- Razzmatazz: all five rooms open simultaneously for OFFSónar, with different promoters taking over each room. One of the most intense nights of the year.
- BARTS: the intimate concert venue on Avinguda del Paral·lel runs quality underground events during Sónar week.
- Club Moog: small, intense, excellent techno programming all week. Usually the most underground option.
- Input Barcelona: one of the best sound systems in the city, serious techno, runs dedicated OFFSónar nights.
How to Navigate Sónar Week
The ideal Sónar week strategy: buy official festival tickets (day and night separately) as early as possible, then build your OFFSónar schedule around them. A typical day during Sónar week might look like: Sónar by Day (noon to 6pm) → dinner and recovery → OFFSónar at Poble Espanyol or a club (midnight onwards) → Sónar by Night (if you have the stamina, starts midnight at Fira Gran Via).
Sónar week attracts the music industry: DJs, producers, label managers, promoters, and serious electronic music fans from around the world. The level of the crowd is unlike any other week in Barcelona. You'll hear more interesting music conversations at the bar during Sónar week than at any other event.
Timing and Logistics
- Sónar by Day: noon to 10pm at Fira Montjuïc. Get there via cable car from Paral·lel metro or Uber/taxi.
- Sónar by Night: midnight to 8am at Fira Gran Via. Take the L9 metro to Fira Barcelona station.
- Poble Espanyol (OFFSónar): requires taxi or Uber. No direct metro. The Sónar official shuttle also stops here on some nights.
- Accommodation: book months in advance. Barcelona fills up completely during Sónar week and prices triple.
- Footwear: Poble Espanyol has cobblestones throughout. Comfortable shoes are not optional.
Insider Tip
Buy Sónar tickets the moment they go on sale in January. They sell out completely, especially night tickets. For OFFSónar, Poble Espanyol events are the most prestigious and those also sell out weeks ahead. Follow promoters like Elrow, Circoloco, and Movement on social media for ticket drops as soon as the OFFSónar lineup is announced (usually April/May).
Essential Tips for Sónar Week
- Buy everything in advance: official Sónar tickets sell out. OFFSónar Poble Espanyol events sell out. Don't assume you can buy at the door.
- Get a day ticket and a night ticket: they are separate. Night tickets are more in demand.
- Research OFFSónar when the lineup is announced (usually April/May): the programme changes each year and some nights are significantly better than others.
- Comfortable shoes: Poble Espanyol has cobblestones everywhere. Factor that into your footwear choice.
- Pace yourself: a full Sónar week is 4+ days of intense music. Build in recovery time.
- Book accommodation early: ideally 6+ months in advance for good options at reasonable prices.
Sónar week is the single most exciting week in Barcelona's cultural calendar. If you care about electronic music and haven't been, 2026 is the year to fix that.
