Haven Kats Noord is a beach-entry shore dive in Kats, Zeeland, where the entry starts near the harbour mouth and the route runs diagonally left across overgrown blocks before fading into sand. It is a North Sea site for experienced divers who are comfortable with strong current, very low visibility, and a rougher bottom than a tropical reef. The draw is the mix of block structure and sandy patches, which makes the dive rewarding both when you are working the blocks and when you settle onto the sand.
