Undersea Festival returns to Terra Mítica with eight stages, 14 hours of music and a giant pool at the heart of the venue
Undersea Festival has unveiled the full details of its second edition: on 13 June 2026, Terra Mítica theme park in Benidorm will again host Spain’s only music event of its kind, blending electronic music, reggaeton and an aquatic experience under one roof. After drawing 5,000 attendees in its debut year, organisers are now targeting more than 8,000.
The festival expands from six to eight themed stages. The Main Stage will feature the top national reggaeton and chart DJs; Warhol brings a tech house pool party; Pitote Club fuses techno with classics; Ocean White takes guests back through the best tracks of the 2010s; Remembers of Alonis revisits the 90s and 2000s with DJs including Miguel Serna and Ismael Lora; and Alonis Barrakus pays tribute to the traditional 'terreta' festivals and Moors and Christians celebrations. Two additional stages will be announced via official social media channels. The Los Reinos de Pandora area will feature a giant swimming pool at the centre of the site, allowing thousands of attendees to dance in the water. After 14 hours of non-stop music — running from noon until 2 AM — an exclusive after-party for 1,500 people will take place inside the Pyramid of Cheops, followed by an open after-party at Ku club.
