Mount Apo Hot Springs are found on the lower slopes of Mount Apo — the Philippines' highest peak at 2,954 meters — in Davao, where calcium-sulfate geothermal waters emerge from volcanic bedrock within the Mount Apo Natural Park, home to the Philippine eagle and extraordinary concentrations of endemic orchid species. The springs form clear mineral pools in mossy montane forest of the sacred volcano revered by indigenous Bagobo people, whose traditional beliefs connect geothermal energy with ancestral spiritual power. Bathing in calcium and sulfate-rich waters at the foot of the Philippines' highest mountain, with cloud forest draping the slopes above, is an experience of extraordinary wild grandeur.
Insider tip — On the slopes of Mount Apo, the Philippines' highest peak, these sulfurous springs at 42°C are nestled within primary rainforest and cloud forest, accessible after a short trek through endemic-species habitat. The waters cut through volcanic rock exposures, forming natural rock-rimmed pools that fill with mineral-rich steam in cool morning air. Guides are mandatory and double as naturalists who can identify the extraordinary birdlife of the Apo wilderness.
