SON Estrella Galicia Posidonia Festival Returns to Formentera

The SON Estrella Galicia Posidonia festival makes its much-anticipated return to the stunning island of Formentera, running from October 3 to 5, 2025. This unique event stands out not only for its vibrant musical lineup but also for its unwavering commitment to sustainability and positive impact on the local ecosystem. Limited to just 350 attendees each day, the festival promises an intimate experience for those lucky enough to secure a ticket.

A Disruptive Format

This year's festival showcases a completely innovative format that distinguishes it from traditional music festivals. The lineup features both renowned and emerging artists, each selected for their quality and originality, embodying the spirit of Estrella Galicia. The secret lineup is a hallmark of the festival, ensuring a fresh and exciting experience for attendees.

Gastronomic Delights

Working closely with local chefs, the festival will present a reinvented culinary experience that emphasizes fresh, locally-sourced ingredients. Attendees can expect dishes created with products from the region, expertly paired with Estrella Galicia beer—a brand that reflects both local heritage and international presence, now enjoyed in over 70 countries including the United States, Brazil, the United Kingdom, and China.

Commitment to Sustainability

Since its inception in 2017, SON Estrella Galicia Posidonia has prioritized responsible tourism and local ecosystem protection. The festival closely collaborates with the Save Posidonia Project, which aims to protect this critical marine plant, essential for the area's environmental health.

Moreover, the festival partners with numerous local entities, suppliers, and producers, ensuring that its economic and social impact is genuinely positive. For the second consecutive year, SON Estrella Galicia Posidonia has achieved TRUE Platinum certification, making it the first Zero Waste festival globally, as recognized by GBCI® (Green Business Certification Inc.™). This ambitious program, initiated during the 2024 edition of the festival, aims to minimize waste and achieve carbon neutrality, a goal the festival has maintained since 2021.

Building a Positive Impact

Estrella Galicia, the flagship brand of Corporación Hijos de Rivera, has been recognized as a BCorp since 2024. The company has developed a comprehensive strategy to create positive impact in five essential areas: Pride of Origin and Community, Meaningful People, Resilient Planet, Responsible Allies, and Essential Governance. This commitment not only reinforces the festival's ethos but also highlights its role in fostering a well-rounded approach to environmental and social responsibility.

Join us at Formentera for a festival experience that seamlessly blends music, gastronomy, and sustainability—an event where enjoyment goes hand-in-hand with ecological awareness and community engagement. #SONEstrellaGaliciaPosidonia
