Formentera is preparing for the 10th edition of the Qué Celeste Festival, an annual event that combines culture, environmental awareness and community participation.

This year's programme will place a particularly strong emphasis on marine conservation, biodiversity, recycling and citizen science, with activities taking place throughout September and the main festival programme scheduled for September 18 and 19.

Among the initiatives are a beach cleanup, a marine science activity with researchers from the University of the Balearic Islands, workshops focused on Posidonia, environmental art created from recovered waste and the creation of a new butterfly garden in Sant Ferran.

The programme is being developed by the Qué Celeste association together with Ibiza & Formentera Preservation and other environmental and cultural organisations.

Ten Years of Qué Celeste

The 2026 edition marks the tenth anniversary of Qué Celeste, which began in Formentera as a community initiative focused on protecting the island's natural environment while creating space for culture and artistic expression.

The festival has developed a distinctive identity by bringing together environmental activism, music, visual art, workshops and public participation.

Rather than treating environmental protection as a separate subject, Qué Celeste places it at the heart of its cultural programme.

The organisers say the anniversary provides an opportunity to continue that approach while bringing new scientific and artistic perspectives to the island.

Beach Cleanup at S'Estufador

The first activity supported by Ibiza & Formentera Preservation will take place on Saturday, September 12, with a beach cleanup at S'Estufador.

Participants will meet at 10am at the church of La Mola before heading to the coastline, with the activity scheduled to run until midday.

The cleanup is free and open to anyone who wants to take part, and advance registration is not required.

According to the organisers, marine currents regularly bring waste into the area, making the cleanup a practical way for volunteers to see first-hand how rubbish moves through the marine environment.

Microplastics and plastic pellets are among the materials repeatedly found during beach cleanups around Formentera, alongside items such as containers, bottle caps and cigarette butts.

Science Comes to the Coast

One of the most distinctive activities will take place on Friday, September 18, when members of the public will have the opportunity to join researchers studying the health of the Balearic coastline.

The activity, running from approximately 9am to 1pm at S'Illa de s'Aigua Dolça, forms part of the Coastal Health Monitoring Scheme developed by the University of the Balearic Islands.

Participants will be accompanied by UIB biologist and ecology professor Samuel Pinya and will observe marine organisms and learn how scientists assess the condition and resilience of coastal ecosystems.

The programme includes practical observation in the water, giving participants a direct introduction to the methods used to study marine biodiversity.

Participation is free, but registration is required.

A Closer Look at Mediterranean Marine Life

The scientific activity is designed to make environmental monitoring more accessible to the public.

Rather than simply presenting research findings, participants will have the opportunity to observe marine species and discuss what those observations can tell researchers about the condition of the Mediterranean.

The organisers say the experience is intended to show how scientists interpret the sea and how long-term monitoring can reveal changes that may not always be obvious from a single visit.

The activity is particularly relevant in the context of rising concern about marine temperatures, biodiversity and the resilience of coastal ecosystems.

Qué Celeste organisers have also highlighted the importance of continuing to observe how increasing sea temperatures may affect marine habitats over time.

Posidonia Takes a Central Role

Posidonia oceanica will also feature prominently in the festival programme.

On Saturday, September 19, a workshop organised with GOB Formentera will focus on identifying Posidonia flowers during a snorkelling activity.

The session, scheduled from midday to 2pm, will allow participants to explore the marine environment while learning more about one of the Mediterranean's most important seagrass species.

Posidonia is particularly significant in the Balearics because of its ecological role in maintaining marine habitats, supporting biodiversity and helping stabilise coastal environments.

The workshop combines direct observation with environmental education, giving participants the opportunity to learn about the species in its natural setting.

From Beach Waste to Art

Another major element of this year's programme will bring environmental concerns into the world of visual art.

Fourteen artists from across the Balearic Islands will participate in a collective exhibition dedicated to the reuse of waste and recovered materials.

The group will include five artists from Formentera, five from Mallorca, two from Menorca and two from Ibiza.

The exhibition will open on Sunday, September 20, at 8pm at the Centre Antoni Tur "Gabrielet" in Sant Francesc and will remain on display until September 27.

Turning Discarded Materials Into Creative Work

The participating artists will work with materials recovered from beaches and other sources of waste.

The exhibition will include pieces incorporating plastics, recycled glass, old candles, fishing nets and other discarded materials that would otherwise have remained waste.

The concept is closely aligned with one of Qué Celeste's long-standing themes: using art to make environmental problems more visible.

The organisers acknowledge that artistic work cannot solve the problem of marine pollution on its own, but argue that it can help keep the issue in public discussion and encourage people to reconsider how waste is produced, used and discarded.

A Second Meeting of Recycling Artists

The Formentera exhibition follows the first Meeting of Recycling Artists and Craftspeople held in Menorca in November 2025.

That initial gathering brought together artists and craftspeople from the four Balearic Islands to exchange ideas about techniques, creative processes and the reuse of discarded materials.

The Formentera event provides a continuation of that inter-island collaboration.

It also demonstrates how environmental initiatives can create cultural connections between the different islands rather than remaining focused on a single local community.

Building a Butterfly Garden in Sant Ferran

The environmental programme will conclude on Saturday, September 26, with the creation of a new butterfly garden at the Espai Cultural de Sant Ferran.

The initiative forms part of Ibiza & Formentera Preservation's "Butterflies for Biodiversity" project.

The garden will include aromatic plants selected to encourage butterflies, bees and other pollinators.

The foundation says the new installation will be its second butterfly garden in the Pitiusas under the project, which has involved planting almost 2,000 aromatic herbs across Ibiza and Formentera since 2014.

Why Butterflies Matter

The butterfly garden is more than a decorative project.

Butterflies, bees and other pollinators play important roles within ecosystems and can also serve as indicators of biodiversity and environmental change.

Creating small habitats with suitable plants can provide food and shelter while introducing residents and visitors to the relationship between plants, insects and wider ecological systems.

The organisers also see the project as an environmental education tool, particularly because it creates a visible example of how biodiversity can be encouraged in a community space.

More Than Music

Although music remains part of the identity of Qué Celeste, the 2026 programme goes well beyond concerts.

The festival includes family activities, environmental workshops, scientific outreach, audiovisual art, recycling initiatives and public participation.

Among the other activities planned for September 18 and 19 are a family-oriented Play Wild programme, a bicycle repair workshop, environmental video art and talks presenting the results of coastal health monitoring.

The combination reflects the festival's longstanding idea that environmental awareness can be approached through many different forms of culture and participation.

Community Participation Is at the Heart of the Festival

Volunteer involvement remains an important part of the event.

The organisers have stressed that the programme could not be delivered without collaboration between associations, specialists, artists and local volunteers.

This year, volunteers are also being invited to help prepare decorations made from materials collected during beach cleanups.

That process turns environmental action into part of the festival itself, with recovered waste becoming creative material for the event.

A Focus on Marine Waste

Marine litter will remain one of the main environmental themes throughout the 2026 edition.

Organisers say microplastics and plastic pellets continue to appear regularly during beach cleanups in Formentera.

The issue is particularly challenging because some waste reaches the island through marine currents, meaning it can arrive even on beaches where visitor numbers are relatively low.

There are also efforts to better understand where some of the waste comes from. The organisers have discussed potential collaboration with university researchers to compare materials arriving on Formentera with waste found in other Mediterranean locations.

That research has not yet been fully developed, in part because of the difficulty of securing sufficient volunteers.

Formentera's Environmental Challenges in Focus

The festival comes at a time when environmental pressures are increasingly visible across Formentera.

Marine litter, warming seas, pressure on coastal habitats and the protection of biodiversity are all issues that require long-term attention rather than one-off campaigns.

Qué Celeste's approach is to bring those subjects into public spaces and make them accessible through participation.

The result is a programme where people can contribute directly to a beach cleanup, join a scientific field activity, learn about Posidonia or see discarded materials transformed into art.

Festival Dates and Main Programme

The main Qué Celeste Festival is scheduled for September 18 and 19, although several associated environmental activities take place before and after those dates.

The official Formentera tourism agenda lists Qué Celeste Festival 2026 for September 18, while the wider programme continues through September 26 and the recycling-art exhibition remains open until September 27.

This expanded programme allows the festival's environmental message to extend across much of September rather than being concentrated into two days.

A Decade of Environmental Culture

Reaching its tenth edition, Qué Celeste has developed into an example of how cultural events can be used to encourage environmental awareness.

Its programme does not separate science, art and conservation into isolated themes.

Instead, the festival brings them together: scientists explain how marine ecosystems are monitored, volunteers remove waste from beaches, artists transform discarded materials into creative work and biodiversity projects create new habitat for pollinators.

That combination gives the festival a distinctly community-driven character.

Formentera Turns Conservation Into a Cultural Experience

The 10th edition of Qué Celeste offers a different way to experience Formentera in September.

A beach cleanup becomes a lesson in marine litter. A snorkelling session becomes a window into scientific research. A pile of discarded materials becomes an art exhibition. A garden becomes a small refuge for butterflies and other pollinators.

The programme is ultimately built around participation rather than simply observation.

For a small island facing growing environmental pressures, that approach gives the festival a purpose that extends beyond its cultural programme.

As Qué Celeste reaches its tenth edition, Formentera is once again putting science, creativity and biodiversity at the centre of a community event designed to encourage people to understand the island's environment and take part in protecting it.
