Itinerary Overview

Explore Earth’s most pristine, vibrant undersea sites

On our South Pacific and French Polynesia tours, you will discover a tropical paradise that is alive and well—as are some of the world’s best dive and snorkel sites—on an expedition from Rangiroa’s sparkling lagoon to the verdant peaks of Tahiti’s neighbor, Moorea. This compact voyage maximizes your time in some of the most vibrant undersea sites in the world. Plus, there’s time to stroll pristine beaches, kayak peaceful coves, and experience true Polynesian hospitality. Dive or snorkel in the Southern Line Islands and see diverse coral, clouds of tropical fish, and healthy predator populations. It is one of the healthiest reef systems in the world and a rare place virtually unmarred by the touch of humans, which is why it was identified by the National Geographic Pristine Seas project as one of the few places researchers can study to see how reefs and undersea ecosystems looked before humans.


  • Spend three full days in the Southern Line Islands, identified as one of the healthiest reef systems in the world by National Geographic Explorer-in-Residence, Enric Sala.
  • Watch on deck as National Geographic Orion navigates the pass in Moorea’s fringing reef to anchor in Opunohu Bay, as Captain James Cook did in 1777.
  • Ride Zodiacs through reef passes, snorkel over beds of giant clams or dive the atolls’ outer reefs in the Southern Line Islands.
  • Hike tropical forest trails or visit ancient Polynesian archaeological sites on Moorea.
