Malepunyo Range (also known as Malipunyo Range,[2] Mount Malepunyo, Mount Malipunyo, Mount Manabu or Mount Malarayat) is an extinct volcano located in Luzon. The mountain range is located between the provinces of Batangas, Laguna and Quezon. It is popular among mountaineers, and has three interconnected destinations: Mt. Malepunyo, the highest; Bagwis Peak (also known as Mt. Susong-Cambing); and Mount Dalaga (also known as Manabu Peak).
The Malepunyo Range is an inactive volcano with its caldera facing south along the vicinity between Lipa City and San Antonio, Quezon. By the 1990s the Malepunyo Mountain Range has been erroneously tagged as Malarayat Mountain Range due to the famous country club located at its western slope named after the Malarayat Hill. Mount Malepunyo is its highest peak located at Barangay Talisay, Lipa City standing at above mean sea level by the ridge of its caldera. The second highest peak of the range is Mt. Dalaga standing at above mean sea level situated at the boundary of Santo Tomas, Batangas and Alaminos, Laguna. During the 1990s, the name was changed by the locals of Santo Tomas to Manabu as a shortened Tagalog phrase Mataas na Bundok which means "High Mountain". At the center of the mountain range is a cliff known as Bagwis Cliff by the locals, yet due to its shape that resembles a goat's breast, it is also called as Susong-Kambing (English: Goat's Breast). In time, mountaineers have also mistakenly named this cliff as Susong Dalaga (English: maiden's breast) which is actually the oldest name of Manabu Peak. A discontinued highway project connecting San Pablo City and Lipa City that traverses the central part of the mountain range made way for the creation of what the mountaineers call as Biak na Bundok (en. Sliced Mountain).
The Malepunyo mountain range has four notable peaks:
Mount Malepunyo is part of Makiling-Malepunyo Volcanic Complex. Mount Makiling, located on the southwest rim of Laguna de Bay, is a 16-kilometer-diameter stratovolcano that reaches 1115 meters above sea level. The cone is formed by a pyroclastic flow, lahar, airfall, and lava deposits. Trachyandesites, trachydacites, and rhyolite are found in the lavas. Welded ash-flow tuffs attest to the eruption's Plinian origin. The La Mesa tuff ring, Bijiang, Mapinggon, and Masaia are all examples of smaller satellitic edifices. To the south of Mt. Makiling lies a severely eroded north-south trending volcanic range, including Mapinggon, Bulalo, and Malepunyo. The higher portions of this composite volcano are dominated by lava flows and breccias, while pyroclastic flows and lahars dominate the eastern flanks. The age of the andesites from Mount Malepunyo ranges from 1.10 Ma to 0.63 Ma (De Boer and others, 1980; Oles and others, 1991).
The mountain range is a famous source of Alamid Coffee due to civet cats that chew on coffee beans and ferments the seeds inside its digestive system. The fermented coffee beans are then excreted along the trails and is cleaned and pulverized for coffee preparation.
The jurisdiction of the Malepunyo Range is separated into two. The Manabu peak is under the jurisdiction of Santo Tomas, Batangas to which its jump-off is at Sitio Sulok. It resembles an easy trail to which a cross has been erected on its summit while a plateau beside it is used as a saddle camp. The southern half is under the jurisdiction of Lipa City, Batangas and the jump-off is located at Sitio Talisay. To which the trail leads to the summit of Mount Malepunyo.[3] A class-4 trail connects Malipunyo to Manabu peak which passes through the vicinity of Bagwis Peak and the grassland plateau leading to Biak-na-Bundok and by the dense forest of the mountain range towards the plateau campsite of Manabu.
