Facilities available at the location include parking, showers, air fills, a rinse station, and boat charter services. Night diving is permitted at this site.

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.

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.
