Anau, also known as 'Mantas Spot,' is a renowned dive site on the east side of Bora Bora, located within the tranquil and protected lagoon. It's famous as a year-round cleaning station, consistently attracting reef manta rays, making it an excellent spot for observing these majestic creatures. Divers begin in a shallow coral garden at just 6 meters, featuring staghorn and honeycomb corals, before descending to a reef slope adorned with 'porites rus' coral, extending to approximately 17-20 meters and transitioning to a sandy bottom.
Several exploration options await. Heading right leads into a narrow channel, which can experience stronger currents but often attracts large manta rays before opening into open water. Continuing straight reveals a submerged pinnacle between 19-24 meters, suitable for swimming around, where hawksbill turtles may be spotted. Behind this pinnacle, a larger channel offers a chance to encounter eagle spotted rays. At depths ranging from 17 to 22 meters, a vibrant clownfish kingdom thrives. A short excursion to the left may reveal variable visibility, as the site's classification as a cleaning station means high concentrations of plankton and particulate matter can cause visibility to fluctuate.
Beyond the mantas, divers may also spot green sea turtles and a variety of typical reef fish amidst healthy coral formations common to French Polynesia's protected lagoons. Anau is suitable for underwater photographers aiming for wide-angle shots and is also popular with snorkelers and freedivers. Divers are reminded to avoid touching mantas, allow them to approach naturally, and minimize exhalation bubbles to prevent disturbance.
