Mount Otemanu is one of two extinct volcanoes at the center of the island.

The Bora Bora Lagoonarium is a natural aquarium on a small motu (island), just east of the main island. (By "natural," we mean that this aquarium isn't man-made. Rather, it's a portion of the actual lagoon). One of the coolest things about this family-owned attraction is that you can actually snorkel on the premises under the supervision of wildlife guides. Beneath the lagoon's surface, you'll spy sharks, turtles, rays and many different kinds of ocean fish.
