Zeelandbrug is a structured reef dive located beneath the bridge pilings of one of Europe's longest bridges. The pylons are colonised from 5 metres down to a maximum depth of 25 metres, with an average depth of 12 metres. Divers must navigate moderate currents tied to tidal cycles, making precise timing around slack water essential. Visibility typically ranges between 3 and 10 metres. Entry is from the shore, though divers should be prepared for potential surf and shore break conditions. Water temperatures fluctuate seasonally between 7 and 20 degrees Celsius, requiring appropriate exposure protection year-round. Always remain aware of boat traffic when surfacing.

Oostnol Colijnsplaat, located at the Zeelandbrug, offers a combination of reef and muck diving within the Oosterschelde tidal system. Divers navigate depths between 7 and 30 metres, with an average of 12 metres. Due to strong tidal currents, planning dives around slack water is essential. Visibility is limited to 1 to 3 metres, requiring proficient compass and buoyancy skills. Shore entry involves navigating a surf break over sharp rocks, necessitating sturdy boots and gloves. Given the water temperatures ranging from 7 to 20 degrees Celsius, a drysuit is recommended for most of the year. Divers should remain aware of potential entanglement risks near submerged structures.

Haven Kats Noord is a shore-entry reef and artificial reef site located at the Zeelandbrug. Divers can explore depths ranging from 5 to 24 metres, with an average depth of 15 metres. The site is situated 650 metres from the shore and features moderate currents. Visibility is typically limited to 2 to 3 metres, requiring close-range navigation of the reef structure. Entry involves navigating surf and shore breaks, necessitating careful planning. Due to the potential for strong currents and entanglement risks, divers should maintain high situational awareness. Parking is available at the site, and tidal timing is essential for a comfortable dive experience.

De Zeeland at the Zeelandbrug offers a combination of natural reef and artificial structures. Suitable for intermediate divers, the site features depths ranging from 3 to 30 metres with an average of 10 metres. Shore entry is standard, though divers must contend with moderate currents that can shift quickly. Visibility typically fluctuates between 3 and 10 metres. Water temperatures vary significantly throughout the year, ranging from 7 to 20 degrees Celsius, necessitating appropriate thermal protection such as a drysuit or thick wetsuit. Facilities at the site include parking and a rinse station. Divers should remain vigilant regarding boat traffic and monitor tidal predictions to manage bottom time effectively.

Willems Reef, located at the Zeelandbrug in the Netherlands, is a reef dive site reaching depths between 5 and 40 metres with an average depth of 15 metres. This site is suitable for intermediate divers who can manage moderate currents and visibility ranging from 1 to 5 metres. Due to the potential for strong currents and a challenging shore break, timing dives with slack water is essential. Water temperatures fluctuate between 7 and 20 degrees Celsius throughout the year. Divers should be aware of entanglement risks and maintain close team contact. On-site facilities include parking, showers, and changing rooms to assist with post-dive comfort.

Haven Kats Zuid is a diverse shore-entry site located at the Zeelandbrug, offering a mix of natural reef, artificial reef, and wreck structures. The site spans depths from 5 to 40 metres, with an average depth of 20 metres. Due to strong currents, this location is primarily suited for intermediate divers experienced in drift diving. Visibility fluctuates between 1 and 10 metres, and water temperatures range from 7C to 20C. Divers should be prepared for surf and shore break during entry. On-site facilities include parking, toilets, showers, a rinse station, and air fills. Always plan dives around slack water to manage currents and optimise visibility.

Kats lange pier is a shore-entry drift dive located at the Zeelandbrug in the Oosterschelde. This site reaches depths between 10 and 45 metres and is suited for advanced divers due to strong currents. Visibility is limited, typically ranging from 1 to 4 metres, requiring careful navigation. The pier structure provides reef features that offer shelter when the current eases. Divers must time their entry precisely to the slack water window to manage the tidal flow. Water temperatures fluctuate between 7 and 20 degrees Celsius throughout the year. Species recorded around this area include seahorses, European common cuttlefish, various sea slugs, lobsters, and crabs.

Kulkenol is a demanding drift dive located at the Zeelandbrug in the Oosterschelde. This site requires boat access and is strictly for advanced divers due to strong tidal currents and depths ranging from 10 to 35 metres. Visibility is limited, typically between 1 and 3 metres. Marine life observed here includes common European Common Cuttlefish, crabs, and snails, alongside less frequent sightings of Thecacera, Grey Sea Slugs, Common Sea Stars, Barnacle-eating Dorids, shrimp, pipefish, European Green Crabs, fanworms, and sea squirts. Compass Jellyfish are rarely encountered. Divers must coordinate entry precisely with slack water to manage the challenging conditions. Water temperatures fluctuate seasonally between 7 and 20 degrees Celsius.
