The crystal-clear waters of the South Pacific afford great visibility for snorkelers and divers. Dozens of types of colorful fish as well as turtles flourish in the warm waters surrounding the island's craggy volcanic rocks. Some of the most spectacular underwater scenery is at Motu Nui and Motu Iti, two adjoining islets just off the coast.
