#10326 Whistling With the Mapu'a 'a Vaea Blowholes in Tongatapu, Tonga
In Houma, just 15 km from Tonga's capital Nuku’alofa, the Mapu’a ‘a Vaea blowholes make for a stunningly spectacular natural phenomenon. Walking along the beach, suddenly a sequence of geysers rises before us. Whoosh, whoosh, whoosh. Ocean water moves through tunnels in the coral reef, finally surging up and whistling as they go. When waves crash into the reef at high tide, the jets cascade almost 30 metres into the air. Hundreds of blowholes line a five-kilometre stretch of Tongatapu's rugged Pacific coastline.
