Vaituha
Vaituha is a small valley in northwestern Eiao (French Polynesia) which empties into a small bay of the same name. This bay is the only reliable anchorage on Eiao.
The interior end of the valley, the site of a seasonally spectacular waterfall, rises steeply to the plateau which comprises much of the center of the island, and is one of the few ascents thereto.
