Apo volcano is the highest mountain in the Philippines, and its name means “Master” or “Grandfather”. There are no known historic eruptions, but the volcano is considered still active.
Apo volcano is an a basaltic to basaltic-andesitic stratovolcano and part of the Central Mindanao Arc, but its volcanic history is poorly known. The densely forested volcano has a flat summit with 3 peaks, the highest of which in the SW is known as Davao volcano and has a 500 m wide crater with a small lake.
The youngest crater is located on the northern peak. Several fumaroles and sulfur deposits occur on the volcano, most notably fumaroles along a fissure on the SE side down to 2400 m elevation.
The Mt. Apo Geothermal Field is a 8.4 km2 geothermal exploration field near Mt Apo, which has been being exploited since October 1996.
Mt. Apo, as the highest mountain in the Philippines, attracts a lot of attention from hikers all over the world.
The Kidapawan-Magpet trail, though one of many trails, is the easiest. The trail will first lead to Lake Agko.
From there, hikers will have to cross Marbel River by walking on
coconut logs without anything to hold for support. The threat of sudden
flashfloods, emphasized by the strong flow of water, will remind the
intrepid hiker that he not climbing an ordinary mountain.
After three hours of river crossing, the first campsite will be
reached – the Mainit Hot Springs. Here, hikers can dip in a hot and
soothing pool. This first campsite must be reached before 3:00 PM,
because the next campsite, Lake Venado, is 5-6 hours away.
Between the two campsites is a thick forest. There, two “killer
trails” will be encountered: the “87-degree” and the “90-degree” trail.
Each taking around 15 minutes, these trails are known to have taken
their toll on climbers. As of 2006, ropes are in place in the ‘90’ to
make it a little bit safer.
After the difficult ascent, the next landscape is the swamp that
heralds the proximity of Lake Venado. This is where many Mt. Apo trails
intersect. The peripheral areas can be used for camping. During summer,
Bagobo tribesfolk would also camp here and put up stalls. Hikers can
choose to camp here, or proceed to the summit.
From Lake Venado,
the summit is still 3 hours of trekking. This time, the environment
changes into a cogon grassland. Then, the otherworldly summit area is
reached. It is rocky, with wild berries, and temperate plants. Beneath
is the old crater of Mt. Apo. The beauty of the summit, the highest
point in the Philippines, has captivated countless climbers.
Going down, the Magpet trail is suggested, even though climbers
typically do a traverse to the Davao (south) side. The Magpet trail,
said to be easiest of all trails to Mt. Apo, will lead to what is called
the Bobbong campsite, and from there, a beautiful waterfalls will be
reached, called the Bongolanon Falls. It appears as if the water curves
and bends, before descending. Weary hikers can swim in the pools
beneath, and it is perfect refreshment after a grand Mt. Apo experience!
