The Mapu a Vaea or "Whistle of the Noble" are natural blowholes on the island of Tongatapu in the village of Houma in the Kingdom of Tonga.[1] When waves crash into the reef, natural channels in the volcanic rock allow water to forcefully blow through and create a plume-like effect. It is one of the highlights of the tours around the island of Tongatapu.[2][3] "Vaea" is the name of the Honorable Vaea Family of nearby Houma.
