Lake Balinsasayao is one of three crater lakes rising 1,000 feet (300 m) above sea level located within the Balinsasayao Twin Lakes Natural Park, an 8,016.05-hectare (19,808.1-acre) protected area covering the municipalities of Valencia, Sibulan, and San Jose in the province of Negros Oriental, Philippines.
Lake Balinsasayao, Lake Danao, and Lake Kabalin-an are part of Balinsasayao Twin Lakes Natural Park, a protected area totaling 8,016 hectares (19,810 acres) created on 21 November 2000 by virtue of Proclamation No. 414 signed by former President Joseph Estrada. It lies within the municipalities of Valencia, Sibulan, and San Jose in the province of Negros Oriental.
The lakes are situated northwest of a narrow mountain ridge, in a caldera formed by four mountains: Mount Mahungot to the south, Mount Kalbasan to the north, Mount Balinsasayao to the east and Guintabon Dome to the west. A normal fault separates Lakes Balinsasayao and Danao while and another fault, the Amlan, is about 1,400 metres (4,600 ft) west of Danao. Four geologic faults also intersect the southern edge of Lake Danao, whose water level is lower than that of Balinsasayao.
