Gunung Masurai, Stratovolcano summit in Jambi Province, Indonesia

Gunung Masurai is a stratovolcano in the Jambi province of Indonesia, rising to 2,916 meters. Near the summit cone sit two crater lakes called Kumbang and Merbuk, which mark the upper part of the route.

Japanese researchers carried out the first documented expedition to the mountain in 1988. Local climbing teams reached the main peak six years later, which opened the mountain to wider exploration.

The mountain feeds the Batang Tembesi, a main tributary of the Batanghari, from springs on its northern side; these springs water villages in Sungai Tenang district at its foot. The name Gunung Masurai is used locally for the whole volcanic complex. Kumbang Lake is the feature climbers most often visit on the way to the summit.

The mountain lies about 110 km southwest of Bangko, in the Kerinci Seblat National Park area spanning Lembah Masurai, Jangkat and Sungai Tenang districts. Kumbang Lake is the usual stop on the way to the main peak at 2,980 m. A road was opened to the shore of Mabuk Lake in 1998.

Two species of tropical carnivorous pitcher plants, Nepenthes spathulata and Nepenthes singalana, grow side by side on the slopes. Finding both species together in the same area is unusual and draws plant enthusiasts to the mountain.
