Mount Butak, Stratovolcano in Malang, Indonesia

Mount Butak is a stratovolcano located at the border between Malang and Blitar regions in East Java, rising to about 2,868 meters above sea level. The slopes display typical volcanic features, and the summit offers expansive views across the surrounding landscape.

The mountain has never erupted throughout documented geological history, despite its classification as a stratovolcano. This dormant status makes it a relatively stable hiking area compared to other volcanic peaks in the region.

The mountain's name is rendered in Javanese script as ꦒꦸꦤꦸꦁꦧꦸꦛꦏ꧀ (Gunung Buthak). The Panderman trail, the most popular route to the summit, starts in Pesanggrahan village, Batu, and shares its first section with the path to Mount Panderman. On 6 October 2020, the Difabel Pecinta Alam (Difpala) group of Lingkar Sosial Indonesia became the first group of hikers with disabilities to reach the summit.

The most popular route starts at the Panderman trailhead in Pesanggrahan village, Batu, and takes 8 to 12 hours to the summit. Pos 1 has a water source and a musala; Pos 3 is the recommended campsite, while Pos 2 is uneven and crossed by hikers. Expect 0–10 °C at night and at most 15 °C by day.

On 6 October 2020, a group from Difabel Pecinta Alam (Difpala) of Lingkar Sosial Indonesia became the first group of hikers with disabilities to reach the summit, after tackling the steep sections between Pos 3 and the savanna and from the savanna to the top.
