Jadini - Diani Beach & South Coast

Maomao Arch, for us, is one of the Poor Knights’ signature dives. It’s not about huge pelagics here, although a striped marlin has been known to cruise past the deeper exit. This site is about the journey, the feeling of moving from one side of the island to the other, all underwater. You drop in on the western side, usually around 10-12 metres, and immediately the light changes as you head into the arch. Inside, the walls pulse with colour – sponges in brilliant oranges and purples, and an unbelievable density of crimson cleaner fish, all flitting amongst the anemones. The arch ceiling is shallow, maybe 5 metres in places, and we love drifting slowly, just taking in the patterns on the rock. It’s here you’ll often find those huge, shimmering schools of pink and blue maomao, so thick they almost block the light from the eastern exit. They’re mesmerising. Coming out the other side, the light explodes back into view, and you’re faced with a jumble of massive boulders. If you head right and down to about 20 metres, there’s a small, open cave, a nice spot to pause and check for a curious short-tail stingray. Visibility averages a solid 16 metres, making the whole experience feel expansive without being overwhelming. This site is perfect for anyone who appreciates the intimate details of a reef and loves a unique underwater transit. It’s a gentle drift, often with little current, suitable for most comfort levels.
