Saronic & Athens divides across three distinct sub-areas: the Athens Riviera, Evia, and the Saronic Gulf. Together they offer an exceptional spread of site types, from accessible beginner reefs and deliberately sunk artificial wrecks to deep technical dives demanding trimix. The Britannic and Monrosa Wreck anchor the expert end, while sites like Kyra Leni and Tripiti reef welcome newer divers. Marine life is rich and observation-backed throughout: Common Octopus, European Common Cuttlefish, Dusky Grouper, and Flying Gurnard appear almost everywhere, with Loggerhead Sea Turtle and Ocean Sunfish adding open-water excitement. Most sites are reached by boat.
