Today, National Geographic Orion arrived in beautiful Rangiroa. Our spirits were full of excitement to experience French Polynesia’s largest atoll and it’s vibrant blue lagoon, which is home to colorful coral, massive gatherings of pelagic fish, roaming sea turtles, and a variety of sharks gliding through the water. This area is well known world-wide as having some of the best opportunities for scuba diving and snorkeling across French Polynesia.
