Undersea Festival breaks records in Benidorm: 14 hours, eight stages and a near-sold-out second edition
Undersea Festival has firmly established itself as one of Spain’s most distinctive experiential events. Its second edition, held on Saturday June 13 at Terra Mítica Benidorm, brought together thousands of attendees over 14 hours of uninterrupted music, entertainment and spectacle — coming close to a complete sellout and surpassing the debut 2025 edition across every metric. The organizers describe it as one of the most innovative events on the national festival calendar, and the numbers from this year appear to bear that out.
The thematic concept for 2026 closed the Atlantis chapter that had defined the first edition and opened an entirely new one. “Los Reinos de Pandora” — The Kingdoms of Pandora — is an apocalyptic, immersive universe that transformed the Iberia Park spaces into a world where each stage functioned as an independent kingdom with its own visual identity, its own sound and its own atmosphere. The transformation was total: set design, videomapping technology, live performances and an overall aesthetic developed entirely by Insuperables Team Show, the production company behind Terra Mítica’s own shows and decorations. Moving from one stage to the next was not just a change of genre — it was a change of world.
The centerpiece of the day was the Main Stage: a 16-meter-high structure with five towers, videomapping technology and detailed thematic design, positioned strategically beside the venue’s central pool. That location was deliberate. The swimming area became a dancefloor, dissolving the boundary between water and music, and reinforcing Undersea Festival's identity as Spain’s leading aquatic music festival.
The remaining seven stages opened progressively throughout the day, building a musical itinerary that spanned virtually every style. Warhol hosted the electronic pool party. Ocean White paid tribute to the biggest hits of the 2010s. Alonis Barrakus brought the festive traditions of la terreta into the heart of the site, with barraca music, a live band and a popular-fiesta atmosphere that offered a striking contrast to the rest of the lineup. Pitote Club took over Terra Mítica’s iconic Arch of Triumph of Rome, converted into a club stage through laser mapping and videomapping technology. Remembers of Alonis, Grüvers x Private Techno and Indie Stage rounded out the program, covering reggaeton, commercial pop, indie, techno, melodic and tech house. The result was a lineup that let every attendee build their own day without ever feeling trapped in someone else’s experience.
The Benidorm festival kicked off with one of its already-established traditions: more than a thousand people were waiting at the gates before opening, eager to be among the first to sit down to a plate of paella and open beer bar. The organizers describe this as a deliberate way to break the ice in the first hour through something that genuinely represents local culture and gastronomy — a nod to la terreta and its way of celebrating. The food offering throughout the rest of the day included burgers, Greek cuisine, baos, Asian fusion, tex-mex and hot dogs. Across the venue, attendees had access to multiple food and drink points, showers, medical assistance, toilets distributed throughout the site, and a pool bar built directly into the swimming area.
One of the most praised aspects of the festival was the ease of moving between stages without sacrificing comfort: shaded areas, rest zones and a spatial layout designed to encourage natural flow between environments. Beyond the music, each space offered its own artistic content in the form of performances, themed decoration, visual shows and live animation.
The geographic reach of Undersea Festival continues to grow: around 30% of attendees came from outside the province of Alicante, confirming the event’s ability to draw a national audience. Benidorm serves as a natural amplifier of this appeal — its hotel capacity and international profile allow many attendees to turn the festival into a multi-day trip, generating a measurable positive impact on local tourism. The event also ran independently of Terra Mítica’s regular park operations, with separate access points for theme park visitors and festival attendees.
The festival closed at 2:00 AM. The organizers are already working on the next edition: Undersea Festival 2027 is confirmed, with first details and ticket sales to be announced through the festival’s official channels.
