Description
Mount Arjuno is a dormant stratovolcano in East Java, Indonesia, reaching 3,339 meters above sea level and one of Java's highest summits. Its peak, Puncak Ogal-Agil, takes its name from a Javanese phrase describing a rock balanced precariously on a cliff's edge. The mountain forms part of the Arjuno-Welirang volcanic complex within the Tahura Raden Soerjo protected forest, approximately 50 km south of Surabaya and 20 km north of Malang. Hikers approach from multiple trailheads — Tretes to the north, Lawang to the east, and Purwosari to the west — with the dry season from April to October considered optimal. All climbers must register online through the SIPENERANG eSIMAKSI permit system, and solo hiking is prohibited (minimum group of three).

Routes
Via Purwosari (Pasuruan) — jalur situs purbakala
Menengah (jalur panjang, penuh situs bersejarah)A route beginning at the Tambak Watu hamlet basecamp, famous for passing dozens of ancient Majapahit-era archaeological sites (e.g. Antaboga cave, sacred petilasan) with a strong spiritual atmosphere, ideal for hikers who want history alongside the climb.
SourceVia Tretes (Pasuruan) — jalur utama
Berat (jalur terpanjang & tersulit, medan berbatu)The most popular and longest route, starting from Tretes (~760 m) through Pet Bocor, Kokopan, and the Pondokan sulphur-mining camp (~2,450 m), then Lembah Kijang up to Arjuno summit (3,339 m); often combined with Welirang for a double summit.
SourceClimbing Experiences
Mount Arjuno (3,339 m) in East Java is the fourth-highest peak on Java, often climbed together with Welirang as a double summit. The Tretes route (Pasuruan) is the most popular but also the longest and hardest, passing the Pondokan sulphur-mining camp and Lembah Kijang. As an alternative, the Purwosari route is famous for passing dozens of ancient Majapahit-era archaeological sites. The videos and write-ups below document real climbs from basecamp to the summit.
