As the sun peeked over the horizon of the beautiful Marquesas islands, National Geographic Orion launched Zodiacs to explore the uninhabited island of Moho Tani. We cruised the coastline of this rarely visited island, and some brave souls went diving below the waves to see manta rays and fish. In the afternoon, guests explored the tikis and meae of Puamau on Hiva Oa. What a day!
