About Moyadons
Moyadons is a boat dive off Riou between Marseille and Cassis, centered on a rocky sec that drops away into a steep wall. The site is known for vivid gorgonian-covered relief, clear-water windows, and a Mediterranean mix of fish and invertebrates. It is best treated as a weather-dependent exploration dive rather than a casual shore stop, with conditions shaped by mistral, wind, and boat access from the Marseille side.
