Rangiroa Atoll, Tuamotu Archipelago

Aug 09, 2018 - National Geographic Orion

Spanning over 80 km in length and over 30km at its widest point, the Rangiroa Atoll is the largest in the Tuamotu Archipelago and the 3rd largest in the world.  Comprised of over 100 motu (small low lying coral and sand islands), Rangiroa harbors a dizzying array of marine life and is home to some rare and endemic species of birds.  Today we concluded our week-long expedition in French Polynesia exploring this magnificent island paradise, both from above and below.

About the Author

Doug Gualtieri


Doug’s passion for the natural world started at an early age in his home state of Michigan. He received two biology degrees from Central Michigan University, and later went on to get a master’s degree in conservation biology. His education led him to study a diverse range of natural sciences, with an emphasis on ecology, animal behavior, and migratory birds. Shortly after leaving the academic world, Doug migrated north to Alaska with his trusty Siberian husky, Koda. He began working as a naturalist in Denali National Park in 1999. For over seven years he has shared his love of Alaska and Denali’s six million acres with Lindblad Expeditions-National Geographic guests, as trip leader for the Denali Land Extension based at the North Face Lodge deep within the park.
