    StandoutExceptional marine biodiversity

    Stonehenge, not the ancient monument, but a series of massive granite boulders just off Cape Town’s coastline, offers a dive that feels genuinely epic. We love how the light filters through the kelp forest here, creating these emerald shafts that crisscross the water. You drop down to a maximum of 19 meters, weaving through gullies and under overhangs, feeling the cool surge of the Atlantic push you gently along. This isn't your typical colourful reef; it's a moody, rugged landscape that buzzes with life. Keep an eye out for the shy pyjama sharks tucked into crevices, or the playful Cape fur seals that often dart past, curious but quick. We've often seen schools of hottentot fish shimmering over the rocks, and if you’re lucky, a broadnose seven-gill shark might glide past in the deeper sections. It’s a site that rewards slower exploration, perfect for divers who appreciate dramatic topography and a chance to spot some larger pelagics in a truly wild setting. The deeper parts with their swim-throughs are our favourite, but even the shallower areas hold plenty of interesting finds.

    Safety Notes

    Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.

    Cold water this month (avg 15°C). Drysuit or thick wetsuit (7mm+) recommended.
