Deep South Whittle Reef - Cape Town & Western Cape

Whittle Reef sits out past Cape Point, a deep-water granite outcrop that screams "adventure." We're talking serious depth here, with the surrounding sand bottom hitting 50 metres or more. The reef itself is a big, lumpy formation of ridges and gullies, some with sand channels snaking down to 45 metres. This spot is definitely for advanced divers comfortable with decompression diving, and probably trimix given the potential depths. Visibility can be hit-or-miss, but when it's good, it’s really good, letting you appreciate the sheer scale of the place. We’ve seen a variety of pelagic fish cruising by, and the rock formations themselves are impressive. It's a proper expedition dive, a chance to explore a truly remote piece of reef.
