Bukidnon is a province in the Philippines that boasts of many wonderful and astonishing natural attractions, most of which are just waiting for the eager explorer to discover.  And among these places, Lake Apo stands out as a wonder beyond compare.

Lake Apo is a crater lake in Barangay Guinoyoran in the City of Valencia in Bukidnon province in the southern Philippines. It is located in a hilly area about 640 metres (2,100 ft) in elevation, about 11 kilometres (6.8 mi) WSW of the city poblacion (town center). Lake Apo was awarded the cleanest inland body of water in Northern Mindanao Region (Region X) in the late 1990s. The green body of water has an estimated area of 24 hectares (59 acres) with maximum depths reaching up to 26 m (85 ft).

The name of the lake come from the Filipino term "apo," meaning elder or grandparent. According to legend, there was a man living in the mountains who assaulted his granddaughter and was punished by the mountain deities for his disrespectful act by flooding the area forming the Lake Apo.

The lake is a crater lake, a basin formed on an old volcanic cone that was later filled with water.[1] It was erroneously reported as a circular rift lake, as this area is not a rift zone but a volcanic area evident by the presence of nearby volcanic peaks like Musuan Peak [7 kilometres (4.3 mi) to the E], Mount Kalatungan [20 kilometres (12 mi) to the NW], Mount Dagumbaan [10 kilometres (6.2 mi) to the SW], Mount Kidongin [25 km (16 mi) to the SW] and the volcanic field east of Pangantucan, Bukidnon [7 kilometres (4.3 mi) to the west]. Another small volcanic cone is located just 2 km (1.2 mi) southwest of Lake Apo.
