There is one spot in the area of Nusa Dua Beach, Bali, called "Water Blow" which is a rock formation where waves colliding onto the rock wall creates a giant splash like the water is "blowing up". Water Blow is located on the Nusa Dua peninsula on Nusa Dua Beach just north of the Grand Hyatt Hotel. This amazing attraction is located on the far edge of the peninsula, on which is usually held a big international invent such as the Nusa Dua Festival, World class exhibitions, and others international events. This area has dangerous cliffs which recently were managed by the BTDC by creating a path and guardrail. Not only that, an open-roofed building and was built at one end of the cliff. The interesting mechanism of Water Blow is that on the cliff, face-to-face with the Indian Ocean, there is a large narrowing gap. When the wave rolls in and hits the cliff, it is caught in the gap and slammed into the top. From a distance it appears like a huge white foam dancing to the top. As larger and faster waves approach, the higher waves tower over the cliff. If not careful, you will get wet.
