Leuser Range, Gunung Leuser National Park

The Leuser Range or Leuser Massif, known as Mount Leuser is a group of three peaks, is the highest mountain in the Indonesian province of Aceh. The range lies to the south and west of the Alas River that flows east from the highlands of central Aceh before turning south through Karo Batak country in North Sumatra province. The Leuser region is of ancient uplifted formations - it is non-volcanic. The region is billed as the largest wilderness area in South-East Asia. It is often assumed, incorrectly, that the highest peak is Mount Leuser when in fact it is Mount Tanpa Nama. Mount Leuser is the lowest of the three peaks. ()
