Dense Oosterschelde breakwater dive with strong current.
Dense Oosterschelde breakwater dive with strong current.
Katshoek is a classic Oosterschelde breakwater dive with a long shore approach, a dense and tropical-looking inner reef, and a much stronger current on the outside. It suits experienced Zeeland divers who are comfortable with tide planning, low visibility, and picking through a hard-substrate reef for the small life that makes the site interesting.
Site Conditions
Safety Notes
Plan the tide, avoid the outside when current is building, and treat the long walk and low-tide exposure as part of the dive plan.
Access Restrictions
Plan the long walk from parking and the low-tide window; the outer side can run hard.
Legal Notes
Free access and no permit are noted, but this is a tidal Oosterschelde site that should be planned around local conditions.
Community notes to help plan your visit.
Scuba Diving
Inside the breakwater is where the sheltered life sits; the outside is for divers comfortable with stronger current.
Freediving
Not a freedive-first site; the current and tidal planning make Katshoek better suited to scuba.
Snorkeling
The shallow bits can be explored from the surface, but Katshoek is primarily a scuba site because of current and low visibility.
