Posidonia 2026 takes place in Athens, Greece, from 2 to 6 June 2026. The exhibition is held at the Athens Metropolitan Expo and is widely regarded as the most important biennial gathering in the global maritime calendar. Below, we answer the most common practical questions about attending Posidonia 2026 this year.
When is Posidonia 2026 taking place?
Posidonia 2026 runs from Tuesday 2 June to Saturday 6 June 2026. The event is held every two years and consistently draws maritime professionals from across the globe for five full days of exhibitions, business meetings, and networking. For anyone working in shipping, offshore, or maritime supply, this is one of the most important weeks of the year.
The timing is deliberate. June in Athens offers favorable weather and positions the event squarely in the middle of the international shipping conference season. With exhibitors and visitors arriving from Rotterdam, Hamburg, Antwerp, Houston, Singapore, and beyond, planning travel well in advance is strongly recommended. Hotels in the Athens area fill up quickly in the weeks surrounding the event.
What is the venue for Posidonia 2026?
Posidonia 2026 is held at the Athens Metropolitan Expo, located near Athens International Airport “Eleftherios Venizelos” in Spata, Attica. The venue is one of Greece’s largest exhibition centers and is purpose-built to accommodate large-scale international trade shows of this magnitude.
The choice of venue reflects the scale of the event. Posidonia regularly attracts thousands of exhibitors and tens of thousands of visitors across its five-day run. The Athens Metropolitan Expo provides the hall space, logistics infrastructure, and modern facilities needed to host a truly global maritime exhibition. Greece itself is a natural home for this event: Greek shipowners control approximately 21% of global tonnage, making the country the world’s largest shipping nation and controller of roughly 70% of the EU fleet of strategically important vessels.
The sheer concentration of shipping power based in Greece means that exhibitors at Posidonia gain direct access to the world’s most influential fleet owners and managers in a single location. No other maritime event brings together as many Greek and international shipowners and shipping executives under one roof.
How do you get to the Posidonia 2026 venue?
The Athens Metropolitan Expo is located approximately 3 kilometers from Athens International Airport, making it one of the most accessible major exhibition venues in Europe. Visitors flying into Athens can reach the venue in under ten minutes by taxi or shuttle. The airport is well connected to most major European and international hubs, with direct flights available from Rotterdam, Amsterdam, Hamburg, London, Dubai, and many other cities.
For those staying in central Athens, Metro Line 3 connects the city center to the airport, and shuttle services typically operate between the airport and the venue during the exhibition period. Taxis and ride-hailing services are widely available throughout Athens and Attica.
If you are driving, the venue is accessible via the Attiki Odos motorway. Parking is available on site. Given the volume of visitors expected during the five days of Posidonia 2026, arriving early in the day is advisable to avoid congestion at peak entry times.
Who exhibits at Posidonia and what can visitors expect?
Posidonia brings together the full spectrum of the global maritime industry. Exhibitors include shipowners and operators, shipyards, equipment manufacturers, technology providers, classification societies, financial and legal services firms, and specialist suppliers across every segment of the maritime supply chain. Visitors can expect a dense, commercially active exhibition where real business decisions are made on the floor.
What makes Posidonia genuinely different from other maritime events is the quality of the decision-makers in attendance. Technical and operations executives travel specifically to Posidonia to evaluate suppliers, compare solutions, and commit to purchases. The event is known for the volume of business concluded directly in its exhibition halls, not just discussed in follow-up meetings weeks later.
For maritime supply companies, Posidonia offers unmatched access to the Greek shipping cluster, which includes over 5,000 companies established or represented in Greece. This cluster encompasses many of the world’s top fleet owners, managers, and service operations. Greek shipowners manage more shipping capacity than any other country, and Posidonia places exhibitors at the center of that community.

How do you register for Posidonia 2026?
Registration for Posidonia 2026 is free of charge for qualified maritime professionals. Visitors are strongly encouraged to register online in advance through the official Posidonia website to ensure quick entry at the venue. Online registration generates a visitor badge, which replaces the need to queue at the entrance and speeds up the admission process significantly.
Access to the exhibition is restricted to members of the Greek and international shipping community. Visitors must present a valid admission ticket, business card, or confirmed online registration badge at the entrance. The organizers reserve the right to refuse access to individuals who are not maritime-related professionals or members of the general public.
A few practical points worth noting before you arrive:
- Children under 16 are not admitted unless accompanied by a parent or responsible adult and must remain with their guardian throughout the visit
- Soliciting business in the aisles, in other companies’ booths, or in public spaces without authorization is strictly prohibited and can result in removal from the event
- Visitor rules and regulations, as well as the evacuation and safety plan, are published on the official Posidonia website and are worth reviewing before attending
For exhibitors, registration and booth booking follow a separate process managed directly through the Posidonia organizers. If you are considering exhibiting for the first time, the official Posidonia website provides full details on available hall space, stand options, and the application process. Given the event’s reputation and the caliber of visitors it attracts, exhibition space tends to be in high demand well ahead of the June dates.
