Greece is one of Europe’s most rewarding shipwreck diving destinations, with everything from a 2,400-year-old ancient cargo wreck turned underwater museum to sunken WWII fighter planes and intact cargo ships you can swim inside. Warm, clear water for much of the year and a recent change in the law have opened up the country’s seabed to recreational divers as never before.
Reviews of Greece and her islands are often mixed. To some it’s a summer party haven; to others it’s a historical treasure trove with tiny tavernas serving food that would embarrass a Michelin kitchen. But there’s a whole other Greece that most visitors never see – the one below the surface.
This guide rounds up the best wreck dives in Greece, what level of diver each suits, and how to plan a trip around them. Whether you’re a snorkeller, a freshly certified Open Water diver, or a deep-wreck specialist, there’s something here for you.
Why Greece Is a World-Class Wreck Diving Destination
Greece sits at the crossroads of the Ionian, Aegean and Mediterranean seas, with more than 13,000 km of coastline and thousands of years of maritime history layered across its seabed. The combination of ancient trade routes, two World Wars and countless storms means the waters here are, as Greece‘s own culture ministry puts it, an “underwater ark” of history.
A few things make it special for divers:
- Warm, clear water. Sea temperatures range from around 15°C in February to 26°C in August, with good visibility at most sites.
- Variety. Ancient amphora wrecks, WWII aircraft, steel cargo ships and natural lava formations – often within the same island group.
- A long season. Many dive centres operate from spring through autumn, with spring offering warm-enough water and fewer crowds.
- History you can touch (almost). Few places let you hover over 5th-century-BC wine jars or a downed wartime fighter in the same trip.
Greece’s diving laws have changed – here’s what that means
For decades, recreational scuba diving in Greece was heavily restricted to protect underwater antiquities. A landmark law passed in 2020 (Law 4688/2020) opened up the country’s seas to divers, lifting depth limits and allowing access to historic wrecks over 50 years old – provided you dive with a certified Greek dive centre.
This is the single biggest change for anyone planning a wreck-diving trip to Greece, and it’s why this article has been updated. Earlier rules dating back to 2005 left much of the coastline off-limits. Today:
- Diving is permitted across most of Greece, with no blanket depth limit (military exercise zones are the main exception).
- Wrecks more than 50 years old may be dived, but only when accompanied by an authorised Recreational Diving Services Provider (a licensed Greek dive centre or club).
- Touching, collecting or disturbing artefacts is strictly forbidden – these are protected monuments.
- Designated historic wrecks and underwater museums have their own rules, fees and accredited operators.
Always book through a licensed local dive centre. They handle the permissions, brief you on the site rules, and keep both you and the wrecks safe. Going it alone on a protected wreck isn’t just dangerous – it’s illegal.
The Best Shipwreck and Wreck Dives in Greece
Here are eight of the country’s standout underwater sites, from beginner-friendly snorkelling to advanced deep wrecks.
1. Peristera Underwater Museum, Alonissos – the “Parthenon of Shipwrecks”
The Peristera wreck off Alonissos is Greece’s first underwater museum and its most famous dive – a 5th-century-BC cargo ship surrounded by thousands of ancient wine amphorae, lying at roughly 22–30 metres in the National Marine Park of the Northern Sporades. It opened to recreational divers in 2020 and fully to the public from 2021.
Discovered by a local fisherman in the 1980s, the Peristera ship was one of the largest merchant vessels of its era – around 30 metres long – and sank around 425 BC carrying some 4,000 amphorae of wine. The cargo still lies spread across the seabed in a breathtaking 25-metre carpet of pottery, now colonised by fish and sponges. Divers describe it, rightly, as diving straight into history.
- Level: Advanced certification required (depth ~29 m).
- Cost: Around €50 site admission, plus the dive cost, paid through an accredited centre.
- Operators: Local Alonissos dive centres such as Triton Dive Center, Seacolours and Ikion run guided visits.
- Can’t dive? Non-divers can experience it virtually via the Information and Awareness Centre in Chora village, with VR tours of the wreck.
This is the headline reason to plan a wreck-diving trip to Greece in 2026.
2. Mykonos – Anna II and Peloponnisos cargo wrecks
For purpose-built wreck diving, Mykonos is one of the best islands in Greece.
- The Anna II is a 62-metre cargo ship that sank in 1995, sitting between roughly 18 and 36 metres. Much of the ship is intact and penetrable, now carpeted in colourful sponges and marine life – a great wreck for less experienced divers building toward wreck penetration.
- The Peloponnisos is an older 64-metre vessel that went down in 1926. Now broken in two and scattered across the seabed at depths reaching around 55 metres, it has become a thriving artificial reef – better suited to advanced and deep-certified divers.
Seasonal note: Autumn storms can shut local operators early. Spring is often the sweet spot – warm enough water, fewer crowds than peak summer.
3. Naxos – the Bristol Beaufighter aircraft wreck
One of the best-preserved wartime wrecks in the Cyclades, the Bristol Beaufighter plane lies off Cape Kouroupas, west of Naxos, at around 34 metres.
The nose has separated from the fuselage and the propeller is gone, but the machine guns and structural details remain clearly visible. It’s a memorable dive for those comfortable at depth.
Getting there: Naxos is a short flight from Athens or a ferry hop from neighbouring islands. Above water it’s quieter than some of its Cycladic neighbours, but it has beautiful beaches and good walking. (Note: Naxos is reached by ferry from islands such as Santorini and Paros – plan your island-hopping route in advance, as schedules vary by season.)
4. Crete – the Messerschmitt and Souda Bay wrecks
Crete offers some of the most atmospheric wreck diving in Greece, much of it tied to the fierce fighting of 1941.
The Messerschmitt wreck – a WWII German fighter that came down off the coast near Malia – rests at roughly 30 metres with excellent visibility. Expect to share it with grouper, cuttlefish and the occasional moray, but there’s plenty of room to explore the well-preserved airframe.
Crete’s wider Souda Bay area is rich in wartime wrecks, and several have been included among the historic wrecks Greece has formally opened to recreational divers in recent years. Dive with a Crete-based centre that knows the permissions and conditions.
Above water, Crete is a destination in its own right – don’t miss the Minoan Palace of Knossos near Heraklion.
5. Thassos – beginner-friendly diving and “Volcano’s Tears”
Not every great underwater site is a wreck. Thassos (or Thasos), in the northern Aegean, is ideal if you’re travelling with mixed-ability divers or snorkellers.
- Seagull Island is an easy, boat-accessible snorkelling spot – perfect for those without an Open Water certificate.
- Volcano’s Tears are mesmerising solidified-lava formations that make for a striking dive for the more experienced.
Thassos is also one of Greece’s greenest islands, with excellent beaches such as Alexandra Beach. It stays relatively low-key but gets busy in summer, so book accommodation well ahead.
6. Alonissos National Marine Park – beyond Peristera
The same protected waters that hold the Peristera wreck – the National Marine Park of Alonissos and the Northern Sporades, the largest marine reserve in Europe – make Alonissos a superb diving base in general. Expect healthy reefs, dramatic underwater topography and a genuine chance of encountering protected marine life. Several historic wrecks in the wider Sporades have been added to Greece’s list of accessible sites, so ask local operators what’s currently open.
7. Kea (Tzia) – the HMHS Britannic (for technical divers)
No serious list of Greek wrecks is complete without the HMHS Britannic, sister ship of the Titanic, which sank off the island of Kea in 1916.
Lying at around 120 metres, it is one of the most coveted wreck dives on Earth – but it is strictly a technical/deep-wreck expedition requiring specialist training, permits and experienced operators, not a recreational dive. For most visitors it’s a bucket-list aspiration rather than a holiday dive, but it underlines just how rich Greek waters are.
8. Newly opened historic wrecks – Greece’s expanding “underwater museums”
Since the 2020 law, Greece’s Ministry of Culture has steadily declared more historic ship and aircraft wrecks accessible to recreational divers – dozens across Kea, Milos, Crete, Chalkidiki, Evia, the Pelion–Skiathos area and the Fourni archipelago.
The country is actively building a network of underwater archaeological sites and museums. It’s worth checking the latest list before you travel, because the map of legally divable history in Greece keeps growing.
Best Time to Go Wreck Diving in Greece
The best time for wreck diving in Greece is late spring through early autumn (May to October), with spring offering warm-enough water and fewer crowds, and late summer offering the warmest sea (up to ~26°C). Many underwater museums and dive centres operate seasonally, so always confirm opening dates.
| Season | Water temp | Diving notes |
|---|---|---|
| Spring (Apr–Jun) | ~17–22°C | Warming up, fewer crowds, great visibility – a favourite among divers |
| Summer (Jul–Aug) | ~24–26°C | Warmest water; busiest and priciest above the surface |
| Autumn (Sep–Oct) | ~24°C falling | Still warm early on; storms can close operators later in the season |
| Winter (Nov–Mar) | ~15°C | Coldest and quietest; most seasonal dive centres closed |

Essential Tips for Wreck Diving in Greece
- Always dive with a licensed Greek dive centre, especially on protected and historic wrecks – it’s a legal requirement on wrecks over 50 years old.
- Get the right certification first. Many of the best wrecks need Advanced Open Water or wreck/deep specialties. Some centres offer the courses on-site.
- Never touch or remove anything. Artefacts are protected monuments; disturbing them carries serious penalties.
- Book ahead in summer – popular sites like Peristera have limited daily slots.
- Check the season. Underwater museums and many dive centres operate only in the warmer months.
- Carry travel and dive insurance, and confirm it covers your planned depths.
- Respect marine parks. Sites like Alonissos sit within protected reserves with their own rules.
Frequently Asked Questions

Yes. Since a 2020 law lifted long-standing restrictions, recreational divers can explore shipwrecks across most of Greece, including historic wrecks over 50 years old, provided they dive with a certified Greek dive centre. Designated underwater museums like Peristera have additional fees and accredited operators.
What is the most famous shipwreck dive in Greece?
The Peristera wreck off Alonissos is the most famous – a 5th-century-BC cargo ship with thousands of ancient amphorae, opened in 2020 as Greece’s first underwater museum and nicknamed the “Parthenon of shipwrecks.” Advanced certification is required to dive it.
Do you need a licence to dive wrecks in Greece?
You need a recognised scuba certification, and for any wreck over 50 years old you must be accompanied by an authorised Greek Recreational Diving Services Provider. Many of Greece’s best wrecks also require Advanced Open Water or deeper specialty certifications.
When is the best time to go diving in Greece?
Late spring to early autumn (May–October) is best. Spring offers warm-enough water and fewer crowds, while late summer brings the warmest sea, around 26°C. Many dive centres and underwater museums operate only in this seasonal window.
Is the Titanic’s sister ship in Greece?
Yes – the HMHS Britannic, sister ship of the Titanic, sank off the island of Kea in 1916 and lies at around 120 metres. It is a technical, deep-wreck expedition requiring specialist training and permits, not a recreational dive.
Final Thoughts
Greece’s reputation is built on what’s above the waterline – the white-washed villages, the ruins, the food. But thanks to a change in the law and a growing network of underwater museums, the country’s seabed is now one of the most exciting frontiers in Mediterranean diving. From the ancient wine jars of Peristera to wartime planes off Naxos and Crete, there’s a lifetime of history waiting beneath the blue.
