Dive Site Location & Key Facts
Dive Site Overview
Bergse Diepsluis stands out as one of few Oosterschelde dive sites entirely free from tidal currents, enabling year-round access. A stable environment here provides ideal breeding grounds for sepia, or cuttlefish, migrating en masse each spring for mating.
Hundreds of divers arrive annually to witness this phenomenon, particularly when water temperatures reach 12°C (53°F). Beyond the seasonal spectacle, a gently sloping dyke wall is abundant with various crabs and lobsters. Divers often discover rich ecological activity along this submerged structure.
An old platform also lies at approximately 10 meters, heavily overgrown with oysters, sea squids, and an array of anemones, providing refuge for conger eels and poor cod. This location welcomes all diver levels, including beginners under supervision, offering a maximum depth of 19 m (62 ft) in its deeper sections.
