Grand Mal Wall - Southwest Coast
Les Jumeaux, or 'The Twins,' off Moorea is one of our favourites for a relaxed drift. It’s not about huge pelagics here; it's about the intricate reef, the sheer abundance of fish life, and the unique topography. We love the feeling of gliding over the two coral peaks that give the site its name, often with a gentle push from the current. The real highlight, for us, is the "cathedral" - an overhang crammed with sleeping whitetip reef sharks. We’ve counted up to eight tucked into the crevices, completely unbothered by us watching. The light plays beautifully through the coral here, casting shadows that make the sharks even more mysterious. Keep an eye out for staghorn and cauliflower corals, they’re particularly healthy. The reef is just buzzing with activity; scissortail sergeants and whitespot damsels dart everywhere, and we often spot longnose butterflyfish picking through the coral. Visibility averages 17 metres, which is decent, but good conditions really make a difference to the colours. This spot is perfect for divers who appreciate a slow pace and love spotting the smaller details alongside the sleeping sharks. Ideal for intermediate divers comfortable with a drift, but generally pretty mellow.
