    StandoutExceptional marine biodiversity

    Cod Hole, within Rowley Shoals, offers a reliable encounter with potato cod, often in significant numbers. We've seen them curious and unfazed by divers, often circling close. The site is a straightforward coral dive, generally suitable for most experience levels, focusing more on these impressive fish than complex reef structures or currents.
