Geology
Mount Apo is a flat-topped, 2,954 m (9,692 ft) (above sea level) high stratovolcano with three peaks. It is the highest peak of the Philippines. The southwest peak has the highest elevation and is topped by a 200 m (656 ft) wide crater that contains a small lake.[5]
The volcanic history of Mount Apo is poorly known but eruptions have produced
Etymology and indigenous peoples
The name of Mt. Apo comes from Apo, a title of respect meaning "revered elder" in various languages of the surrounding

Mount Apo Natural Park
On May 9, 1936, Mount Apo was declared a
UNESCO World Heritage list
In 1987, the National Geographic Society based in Washington, DC in the United States, published a book entitled, "Our World's Heritage", where Mount Apo was noted as a 'site of World Heritage caliber'.[18] The cover of the book also featured Mount Apo's iconic Philippine eagle, along with three other heritage sites which have already been designated as "UNESCO World Heritage Sites".[19]
The Department of Environment and Natural Resources (DENR) submitted Mount Apo on December 12, 2009, for inclusion in the UNESCO world heritage list. The mountain is considered by DENR as the center of endemism in Mindanao. It has one of the highest land-based biological diversity in terms of flora and fauna per unit area. It has three distinct forest formations, from lowland tropical rainforest, to mid-mountain forests, and finally to high mountain forests.[4]
A portion of the eastern slopes are also within the scope of the UNESCO Hydrology Environment Life and Policy (HELP) Network. The Davao HELP Network is focused on building collaboration among watershed stakeholders.
In March 2015, it was taken out from the UNESCO List of Tentative Sites due to the dramatic changes (such as logging, intrusion of companies and urban and agricultural landscape, exploitation, and poaching, among others) it experienced which does not constitute the UNESCO documents that describes the park.[20] Better conservation and a change in the content of documents was recommended by UNESCO.
Climate
The climate at the summit of Mount Apo is alpine (Köppen ETH) as its mean temperature does not exceed 10 °C or 50 °F in any month. It falls under the Type IV climate under the modified corona's classification wherein rainfall is relatively distributed throughout the year. Mean monthly temperature ranges from a low 6.9 °C (44.4 °F) during January to 8.9 °C (48.0 °F) during April. Monthly relative humidity ranges from 78% during March and April and 82% during June and July. Minima reach 2.4 °C (36.3 °F) in January and February.

Bodies of water
Lakes
There are four major lakes in Mt. Apo. Popular of these are Lake Agco, which used to be called "The Blue Lake", and Lake Venado, a well-known mountaineers camping site and a stopover towards the peak. Lake Macadac and Lake Jordan are found in the summit grassland.[24]
Rivers
Mount Apo is a
.Mt. Apo has 19 major rivers and 21 creeks draining its 8 major watersheds (PASAlist.1992). Out of the 19 major rivers, only two has studies as reported by SEA-BMB consultants for the Mt. Apo Geothermal Project Environmental Impact Assessment 1991. According to the report, there are two river ecosystems draining the geothermal site namely: (1) Marbel-Matingao river ecosystem- characterized by narrower river channels at highly elevated areas, much faster water flow, clearer water and rock boulder-rich water beds. The aquatic organisms in the area have expectedly lower biological productivity and species diversity. The report also concluded that this river ecosystem provides much less economic and commercial value for its biological production. The study identified 12 species of fish caught in the area; (2) Kabacan River- Pulangi River ecosystem- characterized by a much wider channels at flat areas, relatively much slower water flow, highly turbid waters and sandy mud river beds.
Waterfalls
The Tudaya Falls is a one-tier 150-metre-high (490 ft) waterfall in Mt. Apo Natural Park.[25] This waterfall flows into the Sibulan River, which flows into the Davao Gulf.
Biological features
The grasslands are characterized by the dominance of Cogon grass (Imperata cylindrica) and Saccharum spontaneum. Other grasses and ferns also thrive, especially along banks of creeks, streams, and rivers and on steep slopes.
Geothermal energy
The Mt. Apo 1 and Mt. Apo 2 geothermal plants, each possess a rated capacity of 54.24 megawatts. Owned and operated by Energy Development Corporation (EDC) the power plants were commissioned in February 1997 (Mt. Apo 1) and June 1999 (Mt. Apo 2) respectively, under a build-operate owner contract arrangement. Located in
The Philippine National Oil Company geothermal plant supplies electricity to Kidapawan and its neighboring provinces, its completion boosted the city's economy.
Watershed and hydroelectric plants
The Tudaya Hydropower Plant
The Tudaya Hydropower Plant, located near the foot of Mount Apo on the Davao side (Sta. Cruz, Davao del Sur), is composed of two run-of-river type plants that will contribute to the energy needs of Mindanao by early 2014.[27]
The Sibulan Hydroelectric Power Plant
The Sibulan Hydroelectric Power Plants have been generating 42.5 MW of clean and renewable energy for Davao since 2010. It is also composed of two run-of the river mini hydro power plants.[28][29]
Sibulan A was completed and commissioned on December 26, 2010. Local residents who are mainly engaged in
Hiking activity
At 2,954 meters (9,692 ft), Mount Apo is the highest mountain (peak) and volcano in the Philippines. It is one of the country's most popular hiking/climbing destinations.
The first two attempts to reach Mt. Apo's summit ended in failure: that of Jose Oyanguren (1852) and Señor Real (1870). The first recorded successful expedition was led by Don Joaquin Rajal on October 10, 1880. Prior to the climb, Rajal had to secure the permission of the
