From large-scale music festivals and outdoor cinema nights to landmark productions and international tours, here is our guide to the best summer festivals taking place in Athens in 2026.
For many travellers, summer in Greece means island hopping, long lunches by the sea and late nights in whitewashed villages. But before the ferries and beach days begin, Athens is worth building into the trip for another reason entirely- its festival season.
From May through to September, the city fills with open-air concerts, major international acts, theatre performances beneath the Acropolis and film screenings in some of the most atmospheric settings in Europe. One week might bring Nick Cave or Florence + The Machine to the stage, another a classical performance at the Odeon of Herodes Atticus or an independent film festival in the heart of the city.
Whether you are spending a few days in Athens before heading to the islands or planning part of your summer around the capital itself, these are the festivals and cultural events worth knowing about early- especially as many of the biggest performances sell out well in advance.
Release Athens Festival
Marking its 10th anniversary this year, Release Athens Festival returns bigger and more ambitious than ever, once again transforming Plateia Nerou into one of the city’s defining summer concert venues. Since launching in 2016, the festival has become a major part of Athens’ cultural calendar, bringing international artists to the Athenian Riviera and drawing both locals and visitors throughout the season.
The 2026 lineup spans multiple genres and generations, with names including Chris Isaak, David Byrne, Jean-Michel Jarre, Pet Shop Boys, Moby, Megadeth, The Offspring, Pantera, Helloween and Sabaton set to perform across the summer. Tickets are available as individual day passes or multi-day packages, making it possible to book around specific artists or plan several nights at the festival.
Release Athens also joins forces once again with SNF Nostos this year, combining the large-scale energy of the festival with the wider cultural program of the Stavros Niarchos Foundation’s annual celebration.
Among the most anticipated performances of the season is Nick Cave’s return to Athens on June 24, expected to be one of the standout nights of the festival. Known for his intense and emotionally charged live shows, Cave remains one of the most compelling performers to see in an open-air setting like this.
Set against the waterfront just outside central Athens, Release Athens has become more than a music festival. For many, it is now part of the rhythm of summer in the city.

Athens City Festival
If Release Athens belongs to the waterfront and late-night concerts, Athens City Festival belongs to the city itself. Returning this May for its fifth edition, the month-long festival once again spreads across Athens with a packed programme of free events taking place in parks, museums, rooftops, courtyards, galleries and unexpected corners of the capital.
Organised by the Municipality of Athens, This is Athens City Festival has quickly become one of the best ways to experience the city beyond the usual landmarks. With more than 300 events taking place throughout May, the festival moves through neighbourhoods including Kerameikos, Kypseli, Thiseio and beyond, giving visitors a different perspective on Athens through music, food, film, art and street culture.
One evening might begin with a rooftop DJ set overlooking the Acropolis, another with an open-air screening in a hidden courtyard, a street party in Kerameikos or a live music performance that keeps the city awake well past midnight. Among this year’s highlights are the opening Athens Urban Picnic at Plato’s Academy, the popular Athens Asian Food Festival, Kerameikos Beat’s after-dark street parties and LTJ Bukem Live in Thiseio.
More than a traditional festival, Athens City Festival feels like an invitation into the rhythm of the city itself. It is as much about discovering neighbourhoods, local venues and the atmosphere of Athens in early summer as it is about the events on the programme.
This year’s edition closes on May 31 with the TiACF Closing Party on Athinas Street, where DJs and open-air sets bring the festival to an energetic finish in the centre of the city.
Date: 1–31 May 2026

Athens Epidaurus Festival
The Athens Epidaurus Festival remains one of the defining cultural events of summer in Athens. For nearly 70 years, the festival has shaped the city’s cultural calendar through theatre, music, dance, opera and large-scale performances staged in some of the country’s most remarkable venues.
Running from June through August, the programme unfolds across both Athens and Epidaurus, bringing together Greek and international artists in a lineup that moves between ancient drama, orchestral concerts, contemporary performance and experimental productions.
In Athens, many of the headline performances take place at the Odeon of Herodes Atticus, the historic open-air theatre beneath the Acropolis where audiences gather for opera, ballet, concerts and theatrical productions in one of Europe’s most atmospheric settings.
This year’s season carries added significance, with the Herodeion expected to close for extensive restoration works following the festival. Among the most anticipated performances at the venue are Lykke Li beneath the Acropolis, Einstürzende Neubauten and the Greek National Opera’s production of Medea.
At Pireos 260, the festival’s contemporary base in Athens, former industrial spaces are transformed into stages for theatre, dance, visual performance and experimental works by leading Greek and international artists. Highlights this year include Einstein on the Beach, Schliemann III by Heiner Goebbels and a special programme marking 20 years of Pireos 260 as part of the festival.
Beyond the capital, the festival continues at the Ancient Theatre of Epidaurus, where audiences travel for performances of Greek tragedy and comedy staged in one of the world’s most important ancient theatres. This year’s programme includes productions of The Persians, The Bacchae, Alcestis, Peace, The Trojan Women and Antigone.
Moving between ancient theatres, industrial stages and open-air performances beneath the Acropolis, the Athens Epidaurus Festival remains deeply tied to the identity of summer in Athens.

Ejekt Festival
For another major night of live music under the Athens sky, Ejekt Festival returns to Plateia Nerou this summer with one of its strongest lineups in recent years. Since launching in 2005, the festival has become one of Athens’ biggest live music events, known for bringing international acts to the city’s waterfront and drawing large crowds each summer.
Set against the coast just outside central Athens, Ejekt has built its reputation on large-scale open-air concerts with a strong alternative and indie focus, combining major headline performances with the atmosphere of a European summer festival.
This year’s edition is headlined by Florence + The Machine, with John Legend, London Grammar and Sleaford Mods also joining the lineup for what is expected to be one of the standout concert nights of the season.
Part of what continues to make Ejekt so popular is its setting. As the sun goes down over the waterfront and thousands gather along the coast for live music, the festival captures a side of Athens in summer that feels energetic, relaxed and distinctly tied to the city’s outdoor culture.
For travellers planning part of their summer around live music in Athens, Ejekt remains one of the essential dates on the calendar.

Athens Open Air Film Festival
As the heat settles over Athens and evenings begin stretching later into the night, the Athens Open Air Film Festival returns as one of the city’s most loved summer traditions. Back for its 16th edition in 2026, the festival once again transforms Athens into a city-wide open-air cinema, with free screenings taking place in gardens, museum courtyards, pedestrian streets, parks, rooftops and unexpected corners of the capital after dark.
Few events feel so naturally part of summer in Athens. One night might lead to a restored classic screened in a neoclassical courtyard, another to a cult favourite beneath the Acropolis or a late-night film shown in a public square filled with locals and visitors alike.
More than simply a film programme, the festival has become part of the rhythm of the city during summer- an invitation to experience Athens differently once the temperatures drop and the streets fill again at night.
Following last year’s anniversary edition, which included more than 50 free screenings across the capital, this year’s programme is expected to once again combine restored classics, cult films, crowd favourites and landmark cinema in some of the city’s most memorable outdoor settings.
Relaxed, nostalgic and distinctly Athenian, the Athens Open Air Film Festival remains one of the most atmospheric cultural events of the summer season.

Athens International Film Festival
As summer in Athens begins giving way to September, the city’s cinematic calendar shifts indoors with the return of the Athens International Film Festival. Better known locally as Νihtes Premieras (Opening Nights), the festival has long marked the beginning of the new cultural season in the capital.
For more than three decades, the festival has brought together Greek premieres, international festival favourites, independent cinema, documentaries, retrospectives and some of the most anticipated films of the year. Screenings, talks and tribute programmes unfold across cinemas in central Athens, drawing directors, critics, cinephiles and audiences back into the city after the summer months.
Unlike the relaxed atmosphere of open-air screenings earlier in the season, Opening Nights feels more focused and cinematic- a return to dark theatres, late-night premieres and carefully curated programming centred around contemporary film culture.
It is also where many award-winning films from Cannes, Venice, Berlin and Sundance make their Greek debut, while emerging directors and independent productions are introduced to local audiences for the first time.
More than simply a film festival, Athens International Film Festival signals a shift in the mood of the city itself. Summer may still linger in the streets, but culturally, this is when Athens begins moving into a new season.

Art Athina
For a different side of Athens during festival season, Art Athina brings the focus to contemporary art, design and culture. Returning in 2026, Greece’s leading contemporary art fair once again gathers galleries, artists, curators, collectors and cultural institutions for one of the city’s most important cultural events beyond the music and performance calendar.
As one of Europe’s longest-running contemporary art fairs, Art Athina has become an important meeting point between the Greek and international art scenes, offering a look at the ideas, artists and creative practices currently shaping contemporary culture.
Held at the Zappeion Megaron, the neoclassical landmark in the centre of Athens, the fair brings together galleries from Greece and abroad across a programme that includes contemporary art, installations, video works, design, performance and experimental projects.
More than a traditional art fair, Art Athina also unfolds as a wider cultural platform, with talks, screenings, curated projects and live events running alongside the gallery presentations. The result feels accessible not only to collectors and industry insiders, but also to visitors wanting to experience a more contemporary and creative side of the city.
For travellers interested in art, design and Athens’ evolving cultural identity, Art Athina remains one of the clearest expressions of the capital at its most international and current.
