Mount Mantalingajan

Mount Mantalingahan (or Mantalingahan or Mantaling) is the highest mountain in the island province of Palawan in the Philippines, with an elevation of 6,844 ft above sea level, its ranked 68th-highest peak of an island on Earth and 10th-most prominent mountain in the Philippines. Located in the southern part of Palawan Island that forms the highest part of the Beaufort Mountains Ultramafics geological region, a series of ultramafic outcrops of Eocene origin, of which Mount Victoria forms the largest contiguous land area. The peak of the mountain is the highest point on Palawan island.

The mountain forms the center of the Mount Mantalingahan Protected Landscape (MMPL), a national park covering the entire Mantalingahan Mountain Range. The protected area status of MMPL was proclaimed on June 23, 2009, by virtue of Proclamation No. 1815. The protected area covers an area of 120457 ha. The entire park is currently listed as a tentative site for UNESCO World Heritage Site inscription.

Continuing discoveries of new species of plant and animal from the mountain highlight its tremendous ecological value and the importance of maintaining such protective zones in the face of constant logging and mining pressures. The pitcher plant species, Nepenthes mantalingajanensis, described in 2007, is named after the mountain itself. In May 2018, UNESCO formally began the process which would possibly declare the landscape a world heritage site by 2020.
