Amposta hosts the festival’s main performative activities -musical and audiovisual performances, sound actions, and artistic installations- while various natural spaces in the Ebre Delta and other villages across Terres de l’Ebre (Miravet, Paüls, Roquetes, Sant Jaume d’Enveja, Xerta, la Sénia, Tortosa, Campredó, and Ulldecona) also welcome performances, sound interventions, concerts, and installations. Eufònic Pro, in Tortosa, features presentations, roundtables, and quick meetings between professionals, along with more informal activities such as artist talks over vermouth and project showcases. Eufònic Campus,  on the other hand, offers a series of workshops and participatory activities deeply rooted in the local context.

The fourteenth edition of the festival will take place from July 10 to 13, 2025, with the main days in Amposta and Eufònic Pro in Tortosa on July 10 and 11. The now traditional Pòrtic Eufònic will be held the weekend before, from July 3 to 6, featuring openings of installations and other activities in unique venues, along with the subprogrammes Eufònic Terra, Co-vision and BotCamp.

Most activities are free of charge, with only the musical and audiovisual performances on Friday, July 11 and Saturday, July 12 in two venues in Amposta (the Auditorium and the Ballroom at La Lira) requiring a ticket. Two types of festival passes will be available: one-day and two-day.
