Castle

Castle really delivers on its name; we think it’s one of the most fun topographical dives in KZN. Dropping down, you’ll find yourself in a maze of pinnacles and buttresses that make you feel like you’re exploring ancient ruins. The swim-throughs here are excellent, narrow enough to be exciting without feeling claustrophobic, and we’ve often seen big Potato Bass lurking in the shadows of the overhangs. Keep an eye out for the smaller stuff too; the nudibranchs are always a treat, and we've spotted some brilliant Flameback Angelfish darting between the corals. It’s a site that rewards multiple dives. Each time you go, you find a new gully or a different corner where a Spotted Grouper might be hanging out. The currents can pick up, so it's best for divers comfortable navigating a drift, but the structure offers plenty of places to duck in and shelter. Our favourite time to dive it is mid-morning, when the light streams through the gaps in the reef, illuminating the schools of Indian Mackerel and Springer. We've even been lucky enough to see Grey Nurse Sharks cruising through during their season.
