Depart mid-afternoon for the island of Bora Bora, a distance of 20 miles (about two hours). A lagoon and a barrier reef surround the island, while two peaks, which constitute the remains of an extinct volcano, define the centre of the island. Explore the island by land, and walk to the summit of Mount Otemanu, for a spectacular view of the lagoon and its amazing colours. In the evening, explore the inside of the reef by tender and watch the shark feeding, before departing on an evening flight to Tahiti.
