FAQ
What certification do I need to dive Marathon Reef?
Marathon Reef is ideal for Open Water divers and even Discover Scuba Diving participants, with interesting terrain starting from 3 to 4 metres and the reef edge dropping to 20-26 metres. The gentle conditions and moderate depths make it one of the best training sites in the Athens region.
When is the best time to dive Marathon Reef in Greece?
June through September offers the best conditions with water temperatures of 22 to 26 degrees Celsius and calm seas. The reef is diveable from May to October. Summer months bring the warmest water and longest daylight, while September and October often offer the clearest visibility as summer plankton blooms subside.
Is Marathon Reef connected to the ancient Battle of Marathon?
The reef lies off the coast of Marathon Bay, the very waters that the Persian fleet sailed into in 490 BC before the famous battle. While the underwater terrain has no direct battle artifacts, diving here adds a unique historical dimension. The ancient tumulus of the fallen Athenian warriors is visible from the water, making this a dive where history and nature converge.
What certification do I need to dive Saronida Cave?
An Advanced Open Water certification is recommended, ideally with cavern diving experience. While the maximum depth is only 25 metres, the overhead environment requires good buoyancy control and comfort in enclosed spaces. Local dive centres offer guided cave dives with thorough pre-dive briefings.
When is the best time to dive Saronida Cave near Athens?
June through September offers the best conditions, with water temperatures of 22 to 26 degrees Celsius and calm sea conditions. The morning hours often provide the most dramatic light effects inside the cave. Saronida is sheltered from northern winds, making it diveable even when other Athens-area sites are blown out.
