’t Koepeltje

This dive site is perfect for turning your weekend dive into a memorable family trip. Situated near a stunning beach with a swimming area, public toilets, and even a water playground, it offers a convenient and enjoyable experience for divers of all ages.

At depths beyond 20 meters, you'll encounter the diverse marine life that characterizes the Grevelingen area. Keep an eye out for shrimps, rock gunnel, lobsters, sepiola, flatfish, and other fascinating underwater creatures.

Parking is available near the snack bar, which also features a comfortable changing area. From there, a short walk along the dune stairs will lead you to the beach. If you prefer to avoid stairs, an alternative option is to park by the marina, although it will require a lengthier walk to reach the dive site. Speaking of which, the dive site is located just behind the slope.

Access to the water is easy either through the bay or via the jetty, but please note that the jetty is not suitable for jumping off. Once in the water, you have the choice to explore around the head or along the dike to the right. However, it is important to adhere to the recommended maximum depth of 20 meters to ensure a safe and enjoyable dive. Previously, divers could also explore the Dolfijntje area, but with the construction of a marina, it is now a prohibited diving zone.

Below 20 meters, the seabed predominantly consists of sand and sludge, limiting the visibility and marine life. Therefore, it is advised to focus your dive on the shallower depths for a more rewarding experience.

With its convenient amenities, abundant marine life, and beautiful surroundings, this dive site offers an excellent diving opportunity for advanced divers. Located in the Netherlands, specifically in t‘Koepeltje, Inlaag, Scharendijke, Schouwen-Duiveland, Zeeland, it is easily accessible and promises a memorable underwater adventure.
