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.
