Why dive here
With 269+ marine species recorded in the area - including blue sharks, blue whales, dolphins, dwarf minke whales and great white sharks - Giant's Castle offers some of Cape Town & Western Cape's richest diving. Water ranges 14-16°C, warmest February, March, April.
Giant's Castle lives up to its name, a colossal granite formation rising from the seafloor, offering divers a maze of swim-throughs and gullies between 10 and 25 meters. We've often found ourselves exploring its nooks and crannies, spotting everything from shy reef sharks tucked into crevices to schools of hottentot darting around the kelp fringes. The site generally suits those comfortable with moderate surge, as the Atlantic can occasionally make its presence felt here. It’s a good spot to just drift and watch the rock shapes unfold.
Safety Notes
Cold water this month (avg 15°C). Drysuit or thick wetsuit (7mm+) recommended.
