The Papenoʻo (Papenoo) River is a river on the island of Tahiti in French Polynesia.
The river rises in the mountains of Tahiti east of the town center of Papeete and ends on the coast of Tahiti near Papenoo. It is about 20abbr=onNaNabbr=on long and is about 10abbr=onNaNabbr=on wide at the mouth. All the water ends in the Pacific Ocean. The river forms as a little trickle from the little snow melt of Mont Orohena in the center of Tahiti and flows northward toward Arue. As it flows north, it collects more and more snow melt. Eventually, it becomes a 10feet wide river 12abbr=onNaNabbr=on south of the ocean. Once it reaches the Tahiti Freeway, it becomes a 20feet wide river. The river's highest elevation is 4000abbr=onNaNabbr=on in the mountains of Tahiti. The lowest elevation is 2abbr=onNaNabbr=on once the Papenoo River meets the Pacific Ocean.
The river was previously called Vaituaru, "the stream that destroys everything in its path".[1]
