    Anau is one of those spots we talk about constantly when Bora Bora comes up. It’s a genuine cleaning station inside the lagoon, a place where mantas really do show up with remarkable consistency. We’ve been lucky enough to spend entire dives just watching these giants glide in, circling the coral heads, almost posing for their regular scrub-down. It’s pretty special to see them come so close, wings flexing, completely unbothered by our presence as long as you play by the rules – no touching, no chasing, and if you can manage it, try to hold your breath as they pass directly overhead. They really do seem to dislike those big bubble plumes. The reef itself is pretty shallow, maxing out at 18 metres, with a decent spread of staghorn coral providing homes for lots of smaller stuff – we’ve seen arcs of fusiliers, clown tangs, and even an oriental flying gurnard once, fan-like fins spread wide. Visibility averages around 14 metres, which is usually plenty to watch the manta show unfold. This site is perfect for anyone keen to spend time observing these magnificent creatures up close in a calm, protected environment, even if you’re newer to diving.
