GROS MORNE INTERIEUR - Cousteau Reserve

The Lighthouse site is a classic for good reason, though maybe not for the one you think. It's not about huge drop-offs here. We find the real magic happens on that plateau, sitting around 15 metres. Drifting across it, you’ll often spot Blue Surgeonfish grazing, their vibrant colours popping against the corals. Look closely for the smaller stuff too: we've had great luck finding Freckled Anglerfish tucked amongst the coral heads, and the intricate patterns of a Lettered Mitre shell in the sand are always a neat find. The visibility averages a decent 15 metres, often better in the morning. We love this site for its relaxed feel, but keep an eye out into the blue. It’s not uncommon to see a Scalloped Hammerhead cruise by, a real heart-stopper. We’ve also seen Eagle Rays here, sometimes in significant schools, like a silent squadron moving through the water. For divers who appreciate a slow, observational dive with the chance of a pelagic surprise, Lighthouse is a solid choice. It’s not demanding, so you can really take your time and soak it all in.
