Why dive here
With 269+ marine species recorded in the area - including blue sharks, blue whales, dolphins, dwarf minke whales and great white sharks - Alpha Reef offers some of Cape Town & Western Cape's richest wall diving. Water ranges 14-16°C, warmest February, March, April.
Alpha Reef, off Cape Town’s coast, is one of those spots that really highlights the unique geology here. We're talking granite corestones forming two distinct sections, broken up by a sandy gully running east to west. The southern lobe is the more substantial part, sloping up from the south before flattening and then dropping into another gully. It’s a wall dive, but not in the typical tropical sense; think dramatic rock formations with corals clinging to the surfaces. We've seen a fair amount of smaller reef fish darting around here. Depths max out around 3 meters, making it a good choice for newer divers or for a longer, relaxed explore without deep deco stops. Visibility can vary, so we'd suggest picking a calmer day for the best experience.
Safety Notes
