Why dive here
Le Grand Bleu is a pinnacle dive in Nosy Be, Madagascar.
Le Grand Bleu, just off Nosy Be, is a good pick for a relaxed afternoon dive, especially if you're keen on the smaller stuff. We've seen a surprising number of cowries tucked into the crevices here, and it's a reliable spot for Natal Electric Rays resting on the sand. Look closely for Sharptooth Snapper darting among the halodule seagrass. It's not a site that will blow your mind with huge pelagics, but for macro enthusiasts and divers who appreciate a quieter experience, it often delivers.
