Lake Agco

Lake Agco is a small volcanic lake in Barangay Ilomavis, Kidapawan City, Cotabato Province, within Mount Apo Natural Park at the foothills of Mount Apo. Situated at around 1,200 meters elevation among pine forests, it is notable for its sulfuric waters and adjacent geothermal hot springs. The lake and the surrounding Mahomanoy area are known for cool mountain climate, geothermal features, and as a staging area for Mount Apo treks.

Visitors can expect a small, shallow sulfuric lake surrounded by pine forest and grassland within Mount Apo Natural Park. The area features natural hot spring pools and man-made pools fed by geothermal waters where bathing is available, cottages and viewing areas, cool mountain air, and views of Mount Apo. The setting is rustic and natural, with trails connecting the lake, hot springs, and nearby campsites.

Lake Agco is of volcanic and geothermal origin on the slopes of Mount Apo, the highest peak in the Philippines. The area lies within Mount Apo Natural Park, first established as a national park in 1936, and has long been used as a rest and acclimatization camp for climbers ascending Mount Apo via the Kidapawan-Magpet trail.

The lake and Mount Apo foothills are part of the ancestral domain of indigenous groups in the area and are valued for their natural and geothermal features. The site is a well-known local recreation and wellness destination centered on hot spring bathing.
