    Le Trou du Lagon on Moorea is one of those spots we always make time for. It’s a deep, sheltered lagoon basin, maxing out at 18 metres, which means the light always feels soft and diffuse, especially in the morning. We love drifting over the sandy patches, keeping an eye out for sleeping whitetip reef sharks – they’re usually tucked into crevices or just resting on the bottom, easy to spot. The coral rose here is a definite highlight, a huge, intricate formation that draws in all sorts of reef fish. You'll see schools of convict tang and soapfish, and we’ve often found scorpionfish camouflaged perfectly against the coral. It’s a calm, easy dive, perfect for photographers wanting to take their time or for newer divers building confidence. Visibility averages around 19 metres, which gives you plenty of scope to take everything in. Keep an eye on the sandy slopes for leopard rays gliding past.
