Volcanic activity has created a mountainous interior with lots of opportunities for hikers and climbers. Mount Apo is the highest mountain in the Philippines and is located in Southern Mindanao. The inactive volcano is towering 2954 meter (9692 ft) above sea level and home to the Philippine Eagle. The climb to the summit is relative easy and can be done in 3 days. The hike can be undertaken year round, although the best time is during April and May.
Mount Pulog in Luzon is the second highest peak at 2842 meter above sea level of the country. There are four major trails to the summit all managed by the Mount Pulag National Park. A permit from this agency is required and a track can take between one and four days for the return trip.
Climbing the illustrious Mount Pinatubo is a popular day trip from Manila or Angeles. Its an easy climb usually combined with a visit to local hotsprings. One of the worlds most active and smallest volcanos is Taal, located 3 hours south of Manila and situated in lake Taal. Inside the crater of Taal Volcano a lake has formed, which contains high concentrations of sulfuric acid and minerals. The touristic city of Tagaytay is the common starting point for tours to the crater. A short boatride take takes you to the base of the Volcano and from there the hike to the top takes a few hours. Luzon is further home to the Sierra Madre and Balabalasang-Bablaban national parks, both offering great trekking opportunities through pristine rainforest and are still largely undiscovered by mass tourism .
The Bicol region hosts Mount Asog, Mount Isarog and the famous cone shaped Mayon Volcano. Mount Asog and Mount Isarog can be climbed within 2 days, while Mayon Volcano takes 3 days hiking and another 12 hours of steep climbing to the summit.
The infrastructure in most of the national parks is rudimentary and facilities are basic. Trails are usually not or very bad marked so a knowledgeable guide is essential. Accommodation, cooking or toileting facilities in the parks are absent so come prepared and bring plenty of food and drinks. A GPS is also a good investment to follow your progress or get you back home, if your guide turns out to be not that knowledgeable of the area.
