Sonja and Tauono Raela, who live between Paradise Cove and Vaikoa Units, offer unique reef tours in a traditional outrigger sailing canoe. The fee includes a light lunch, and they'll prepare any of the fish you catch for an additional fee, depending on what you want. You may also take your fish back to your guesthouse and cook it yourself.
If you'd like to do any reef walking or fishing with a bamboo rod you must go at low tide; the swimming and snorkeling are better at high tide. Tauono is a sensitive guide more than willing to explain Aitutaki's delicate reef ecology during the four hours the trips usually last. Call the night before to arrange a time.
Tauono and Sonja keep the only organic garden on Aitutaki and it's always worth stopping by to buy some vegetables, herbs, cakes, or fresh fish. Sonja will happily spend time with you providing cooking suggestions and general information on their produce and the cuisine of the islands.
