The Sulfur Vents in Pulangbato, Valencia, Negros Oriental, are natural openings in the earth where sulfuric steam escapes, a reminder of the geothermal activity in the area. The name “Pulangbato” (literally “red rock”) comes from the reddish rocks around the site, colored by sulfur deposits. The vents are often visited along with Pulangbato Falls, just nearby. #smokeymountains #NegrosOriental #tourismph | I Love Dumaguete
