Koningsheim is a challenging wall and drift dive located at the Zeelandbrug in the Oosterschelde. The site features a wall dropping to 25 metres, shaped by strong tidal currents that require precise timing for entry. Divers must navigate in visibility ranging from 1 to 3 metres, making buoyancy control and compass navigation essential. Due to the current and potential for entanglement in debris or kelp, a surface marker buoy is required for this shore entry. Water temperatures fluctuate between 7 and 20 degrees Celsius, necessitating appropriate thermal protection. This site is suited for advanced divers capable of managing strong currents and deep water conditions.

Zeelandbrug in the Oosterschelde offers a challenging reef and wall dive with depths ranging from 5 to 40 metres, averaging 20 metres. This site is suited for intermediate divers due to moderate currents and the necessity of timing dives around slack water to ensure optimal visibility, which typically fluctuates between 3 and 10 metres. Shore entry requires navigating a surf or shore break, demanding a controlled technique. Water temperatures vary significantly throughout the year, ranging from 7C in winter to 20C in summer, making drysuit use advisable for most seasons. Always consult tidal tables before planning your entry to manage the estuary flow effectively.

Oesterputten is a challenging drift and muck dive located in the Oosterschelde tidal system. The site is defined by strong currents that necessitate precise timing with the tidal window for a safe descent and ascent. Divers operate at depths ranging from 13 to 24 metres, with an average depth of 18 metres. Visibility is consistently limited to 5 metres, requiring divers to maintain close proximity to the substrate and demonstrate excellent buoyancy control. Due to the powerful flow and the presence of sharp bottom hazards, this site is strictly for advanced divers. Access is exclusively by boat, and local tidal tables must be consulted to plan dives during the brief slack water period.

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.

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.

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 is an advanced dive site located at the Zeelandbrug in the Oosterschelde. The topography features a mix of reef structures, wreck sections, and artificial reef material. Divers can explore depths ranging from 8 to 40 metres, with an average depth of 18 metres. The site is subject to strong currents, requiring careful planning around slack water. Visibility is variable, typically between 1 and 5 metres. Shore entry requires caution due to potential surf and shore break. Facilities at the site include toilets and air fills, supporting self-sufficient day trips. Water temperatures fluctuate between 7C and 20C throughout the year, necessitating appropriate thermal protection.

Vliete polder pijlhuisje is a demanding drift dive located near the Zeelandbrug. This site features a reef structure that reaches depths between 10 and 50 metres, with an average depth of 25 metres. Divers must contend with strong currents and low visibility, typically ranging from 1 to 2 metres. Shore entry requires navigating surf and a shore break, making this site suitable only for advanced divers. Due to the active boat traffic in the Oosterschelde, the use of a surface marker buoy throughout the entire dive is essential. Tidal planning is critical, and divers should enter close to slack water to manage the current effectively.
