Molokini Crater - Hawaii

Molokini Crater. We’ve heard the whispers, seen the postcards, and yes, it *is* worth the early start. You’re heading out with a dozen other boats, no doubt, but once you slip into that water, the noise fades. Inside the crescent, it’s like diving in an aquarium. The visibility often stretches 40 metres, making it easy to spot the colourful Arc-eye Hawkfish darting among the Pavona coral. We love drifting along the reef, watching the schools of Gendarme fish flicker in the sun. It’s calm, almost meditative, and perfect for getting your buoyancy dialed in. Now, for the real treat, if conditions allow, we head to the ‘back wall’. This is where Molokini really shows its teeth. The wall plunges into the deep, and the current picks up. This is where you might catch a glimpse of a whitetip reef shark patrolling or a sleek Unicornfish cruising by. Keep an eye out for Dragon wrasse tucked into crevices. It’s a completely different vibe out here, more dramatic, less sheltered. Our pick is always the early morning dive; you beat some of the crowds and the light piercing through the water is just something else. Come summer, the waters are at their calmest, but even in winter, Molokini offers a stunning contrast between its placid interior and the thrilling depths of its outer wall.
