This natural aquarium and water park is located on a private island near the Motu Piti Anau, not far from Le Meridien Resort. The family owners run half-day and full-day visits that include swimming with marine animals, ray and shark feeding demonstrations, circle-island tours in an outrigger canoe, and snorkel visits to the famed coral gardens at the southeast end of the main island. Alternatively, visitors can spend half a day just swimming, exploring, and learning about
marine life. The owners also run a small guesthouse, called Pension Lagoonarium, on the main island's east coast.
