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.

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.

Wemeldinge-Oost Linda, located near the Zeelandbrug, offers a varied underwater terrain that combines natural reef with artificial structures. Suitable for intermediate divers, the site spans depths from 3 to 30 metres with an average of 15 metres. Divers experience moderate currents, making this a drift dive location where planning around slack water is essential for safety. Visibility typically ranges between 3 and 10 metres. Shore entry is straightforward, and the site is equipped with parking, toilets, showers, and a rinse station. Due to boat traffic and current strength, a surface marker buoy is strongly recommended. Exposure protection, such as a full wetsuit or drysuit, is necessary given the seasonal temperature range of 7 to 20C.

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 Zuidzijde features a mix of natural reef and artificial structure provided by the bridge columns. Divers can explore depths ranging from 7 to 30 metres, with an average depth of 16 metres. The site is suitable for intermediate divers, offering both shore and boat access. Visibility typically ranges between 5 and 10 metres. Currents are generally moderate but can strengthen significantly as water is channelled between the columns, making slack water entry essential. The site supports night diving and is accessible year-round. Facilities include parking, air fills, changing rooms, showers, and a rinse station. Species recorded around this area include seahorses, cuttlefish, seals, lobsters, and various sea slugs.

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.

Havenhoofd West is a shore-entry reef dive located near the Zeelandbrug. The site features a depth range of 1 to 15 metres and is suitable for intermediate divers. Visibility is variable, typically between 1 and 5 metres, requiring good buoyancy control. A moderate current is present, which necessitates careful planning around slack water. Divers should be aware of potential hazards including boat traffic, entanglement risks, and shifting currents. A surface marker buoy is essential for safety. Water temperatures fluctuate between 7 and 20 degrees Celsius throughout the year. Species recorded around this area include various crabs, lobsters, sea stars, pipefish, and sea slugs, alongside occasional seal sightings.
