Greece – Crete

Crete's best-documented diving is on the north coast. Around the Akrotiri peninsula and Cape Drapano near Chania, fast boats reach sea caves and caverns such as Elephant Cave, Seal Cave and Cathedral Cave, and the steamship Minnewaska lies at Marathi in Souda Bay, one of eleven Greek wrecks opened to visits by the Ministry of Culture in 2022. East of Heraklion, Hersonissos offers the St George wall and a Messerschmitt Bf 109 at 24-28 m, and sheltered Mononaftis Bay at Agia Pelagia has guided shore dives. In Lasithi, dive centres work from Elounda and Agios Nikolaos (Spinalonga, the Mirabello Gulf) and from Sitia, while the south-east around Ierapetra has the WWII cargo ship Rawnsley. Greek law limits where and how you may dive, so always go with a licensed centre.

Facts

• Best season: Roughly April to October; PADI recommends May and September for the best conditions at Hersonissos, and Heraklion Diving Center runs from April to October
• Water and visibility: 19-26 C and 20-40 m visibility around Chania (Blue Adventures); 18-28 C and 15-30 m on the Ierapetra sites (Ierapetra Diving Centre)
• Getting there: Airports: Heraklion (HER) for the centre and east, Chania (CHQ) for the west
• Diving rules: Under Greek law the Archaeological Service can restrict access to Greek waters and allow diving only at specific, limited locations; a Crete tourism page says wrecks over 50 years old are classed as historically significant. Protection of wrecks is set by Law 4688/2020 (Art. 7): no intervention, no collecting or moving of objects. Dive with a licensed centre and check current rules
• Open wrecks and notification: In June 2022 the Ministry of Culture and Sports opened eleven wrecks to visits, among them the steamship Minnewaska at Marathi, Crete. Dive only around the outside, and e-mail the Ephorate of Underwater Antiquities (eea-shipwrecks@culture.gr) at least a day before. The 2021 list of 91 wrecks named seven in Crete (SUNDAY, Beaufighter, Arado Ar 196, an Australian Amphitheater, Pierre Luigi, a German warplane at Gerani, Minnewaska)
• Caves: The sea caves near Chania are cavern or cave dives; a Crete tourism guide says underwater caves and enclosed passages need specialist training, suitable equipment and experienced professional supervision, and that Elephant Cave should only be approached with qualified guides
• Archaeological remains: Sunken remains at Elounda (Olous), Itanos and Koufonissi are of archaeological interest; observe and photograph only, removal or disturbance is strictly prohibited. We found no source on whether recreational diving is permitted there, so they are not mapped
