The word “naglalahao” is a Bicol word that means “to go down or to fall down” and describes the movement of water that falls and flows from the roughly 7 meters high falls. Some people used to call it Hulugan Falls. Several rivers and tributaries including waters that come from crevices of Bulusan Volcano would flow and converge into this falls. The waters from Dino River, Palogtoc Falls and the river inside the De Vera estate, all from barangay San Roque of the municipality of Bulusan, would all flow into this falls. The present administration of Mayor Alfredo Cielo, Jr. is now currently developing this place as an eco-tourism site in conjunction with the development being made in Irosin Lake. An access road to the falls from Irosin Lake is now being made. The falls is about 6.38 kilometers from the poblacion and can be reached from Irosin Lake through bicycles or motorcycles or by trekking through a distance of about 2.38 kilometers.
