Because it does not have lagoon, Rurutu can be approached easily from seaward. It is therefore a popular destination for humpback whales: dozens come every year to mate and give birth to calves. The island has managed to avoid all manner of pollution, including noise. Divers are careful not to disturb the whales, which can reach lengths of more than 15-metres, but the desire to swim with them is too strong to resist. It's a whale lover's dream come true: observing the marine choreography of this protected species and listening to their love songs, in the water or from the specially equipped platforms. Emotion overwhelms the audience during these exceptional moments.
