Lake Danao is a guitar-shaped volcanogeneic lake on the island of Leyte in the Philippines. The lake covers an area of 148 hectares (370 acres) within the 2,193 hectares (5,420 acres) Lake Danao Natural Park, which also includes the Amandiwin Mountains.
The lake is 18 kilometres (11 mi) northeast of Ormoc, a half-hour drive along the San Pablo-Tongonan and Milagro-Lake Danao roads. It was originally named Lake Imelda after First Lady Imelda Marcos and was declared a national park on June 2, 1972 through a presidential memorandum issued by then President Ferdinand Marcos.
