Mambucal Hot Spring Resort lies on the eastern slopes of Mount Kanlaon — the highest peak in the Visayas and an active stratovolcano — above Bacolod City on Negros island, where calcium-rich geothermal waters form cascade pools in primary rainforest within the Kanlaon National Park buffer zone. The resort features seven cold waterfalls and warm thermal pools surrounded by lush tropical forest, with rare Philippine fauna inhabiting the volcano slopes above. The combination of active volcano drama, waterfall swimming, calcium mineral soaking, and Negrense sugar-plantation heritage in Bacolod City creates a uniquely dramatic Philippine hot spring experience.
Insider tip — Mambucal sits at the foot of the active Kanlaon volcano in Negros Occidental, where sulfurous springs at 42°C cascade through a series of natural rock pools surrounded by lush secondary forest. Seven waterfalls thread through the same gorge, allowing a natural circuit of cold plunges and hot soaks within walking distance. Trekking to the upper falls before 8 AM gives you the entire landscape in near solitude.
