Mercurius - Fernando de Noronha

Platax is a site that just feels different, a deep dive with a real sense of exploration. We often drop into the blue here, a slow descent with that deep Caribbean cobalt stretching out around you. The boot-shaped rock formation is your marker, leading you down to where the reef begins to unfold around 25 metres. We love how the light changes down here, a soft, filtered glow illuminating colossal barrel sponges and intricate black coral trees. You'll find generous stands of gorgonians too, swaying gently in the current, and we’ve often spotted eagle rays gliding past in the distance. The overlapping coral growth is truly impressive, a dense, layered ecosystem. For those comfortable with depth, Platax offers a quiet, profound dive experience, a place to really appreciate the scale of the Cousteau Reserve. Just remember your bottom time, because you'll want to soak in every moment.
