You have to see the blue of the lagoon to believe it. Rangiroa is the largest atoll of the Tuamotus in French Polynesia. Its passage is wide enough to accomodate the Aranui3 (see in background). We crossed the Tuamotos - aka graveyard of sailships - on our way north to the Marquesas and then again on our way back to Tahiti. On the way up, we stopped at Fakarawa and on our way down, we stopped at Rangiroa. Fakarawa is popular with divers. Rangiroa has become a regular destination for cruise ships.
