While not the tallest mountain on Raiatea—that distinction belongs to 1,017-meter-tall (3,337-foot-tall) Mount Tefatoaiti—Mount Temehani is the island’s most sacred. And at 772 meters (2,532 feet), it’s plenty scenic, too. But this flat-topped peak’s true claim to fame is the tiare apetahi—a delicate, white, five-petaled flower (related to the Tahitian gardenia) that’s so rare it grows nowhere else on Earth but on this mountain.
