About Den Osse Haven
Den Osse Haven is a shallow Grevelingen shore dive with a sandy start, a steeper line near the breakwater, and a simple route that rewards slow close-in searching. The basalt blocks hold sea squirts, pipefish, gobies, crabs, shrimps, lobsters, and the occasional butterfish, while the western sandy plain also makes it a strong snorkel option on calmer days.
