    StandoutExceptional marine biodiversity

    Itsandra Reef is one of those sites we always recommend for a relaxed afternoon dive, especially if you’re staying near Moroni. The reef itself slopes gently from about 5 meters down to a sandy bottom at 20, making it very comfortable for newer divers or for a long, slow exploration. We love the way the light filters through the shallows, illuminating patches of staghorn coral. Keep your eyes peeled for the smaller stuff here. While a green turtle might glide past, it’s the little characters that really stand out. We’ve spent ages watching the Arenatus wrasses darting about, or spotting the Banded Toby tucked away amongst the coral heads. If you’re patient, you might even catch a glimpse of a Bluestripe Pipefish weaving through the branches. The Blackstriped Cardinalfish often hang out in shady spots, a shimmering school, and the Epaulette Soldierfish are always a striking flash of red. It's not a dive for big pelagics, but for a calm, colourful introduction to Comoran reef life, it’s our favourite. The currents are usually negligible, so it’s easy to just drift and absorb the quiet hum of the reef.
