Pulangbato Waterfalls (literally translate to red rocks), a beautifully unique waterfalls is located in Ocoy Valley in Valencia, a municipality that is just 9.4 kilometers away from Dumaguete City in Negros Oriental. Though not as majestic as Casaroro Falls located in the same municipality, Pulangbato Falls is unforgettable because of the red color of its rocks.
The rocks are yellowish when dry but when they are touched by the water, they turn red. Locals say it is the presence of iron minerals that made the rocks turn red while others say it is the sulphur coming from Mt. Talinis. The water has a slightly rusty smell and your clothes and skin will be stained if it touches the red rocks. If you walk barefoot, don’t be surprised to see that the soles of your feet have turned red. (Source: http://www.thousandwonders.net/Pulangbato+Waterfalls)
