This dive site, Dolfijntje, is named after a former floating restaurant and its associated underwater viewing tank, which allowed glimpses into the marine world. The restaurant closed in 2007 and was removed after a fire in 2009. The site is characterized by its shallow and largely flat topography, making it relatively easy to navigate, but divers must exercise caution due to its proximity to an active harbor entrance where diving is strictly prohibited.
Typical marine life for the Oosterschelde region can be observed here, including various species of crabs, shrimp, flatfish, gobies, and blennies. The shallow bottom is often populated by anemones, mussels, and different types of seaweed and soft corals like dead man's fingers, providing habitat and interest for macro photography.
The best time to visit Dolfijntje for diving is typically during the warmer months, from late spring to early autumn, when water temperatures are milder and visibility might improve. Divers and freedivers should always pay close attention to the restricted harbor entrance area and avoid venturing into it due to boat traffic. Its shallow nature allows for extended bottom times, making it an excellent spot for learning or practicing skills, as well as for macro photography.
