This dive site, Nieuwe Sluis - De Tetjes, offers a unique shore diving experience in the Netherlands. Divers enter from the beach in the corner between the left dam and the dike. Navigation is highly dependent on the tide, dictating whether divers will explore to the left or right. The bottom slopes gradually, reaching depths of up to 40 meters, though the maximum recommended dive depth for this site is 24 meters. Due to its specific topography, the site is known for strong, rotating currents that require careful planning and experience.
The marine life at Nieuwe Sluis primarily features a lightly vegetated, sandy bottom. This environment is particularly notable for the prevalence of brittle stars, which are described as displacing the common starfish in these regions. While large pelagic species are not typical, the site offers interesting macro opportunities for observant divers to spot various small critters and bottom-dwelling organisms.
The best time to visit this dive site is generally during the summer months (June-September) when water temperatures might be slightly milder, though drysuits are recommended year-round. Divers should always consult local tide tables and current forecasts before entering the water. Due to the variable and potentially strong currents, this site is best suited for intermediate to advanced divers comfortable with drift diving and managing challenging conditions.
