6 of the Most Dangerous Mountains in Indonesia to Hike Beyond Rinjani

TEMPO.CO, Jakarta - Home to more than 120 active volcanoes, Indonesia is a true haven for hikers and thrill-seekers alike. While the trails can be incredibly demanding, with steep elevations, unpredictable weather, and rugged terrain, the sweeping views from the top are nothing short of jaw-dropping.

But beauty often comes hand in hand with a new level of toughness, especially in the most dangerous mountains in Indonesia. Beyond the iconic Mount Rinjani, volcanoes like Mount Semeru, Mount Bromo, and Mount Agung challenge even the most seasoned adventurers with their raw power and physical demands.

Here are the top five most dangerous mountains in Indonesia, according to various sources.

6 Most Dangerous Mountains in Indonesia to Hike

1. Mount Semeru, East Java

The highest peak in Java, Mount Semeru, is also widely regarded as one of the most dangerous mountains in Indonesia. Standing at 3,676 meters, the trail passes through dense forests and steep, ashen slopes. Hikers not only struggle with slipping on loose volcanic gravel but also risk exposure to Semeru’s toxic fumes. This is why checking the volcanic activity of Mount Semeru is essential before planning your ascent.

2. Mount Agung, Bali

Mount Agung is Bali’s highest point, rising to 3,142 meters. While the trail is generally well-marked, its nearly vertical incline makes it a physically demanding climb. Of the two main routes—Pura Pasar Agung and Pura Besakih—the latter is widely considered the more challenging. The Pura Besakih trail is longer and tougher, featuring steep, muddy terrain that takes around 6–8 hours to ascend.

3. Mount Kerinci, West Sumatra

Moving on to Sumatra, there’s Mount Kerinci—Indonesia’s tallest active volcano. Its dense jungle, slippery trails, and cold temperatures near the summit already make it one of the most dangerous mountains in the country to hike. While the views are undeniably breathtaking, the final stretch to the summit is a true test of endurance, consisting of loose rock and volcanic ash, with no defined trail.

4. Mount Raung, East Java

From the very start, Mount Raung tests a hiker’s endurance with steep inclines. The trail to the summit also narrows dangerously, flanked by deep ravines on both sides with little room for error. As an active volcano, Mount Raung also poses the risk of sudden eruptions.

5. Mount Latimojong, South Sulawesi

The highest mountain in Sulawesi, Mount Latimojong, stands at 3,478 meters. Far less commercialized than many other mountains in Indonesia, Latimojong offers a raw and demanding hiking experience that spans several days. The trek winds through thick jungle, steep ridges, and river crossings. Due to its remote nature, infrastructure is minimal and limited.

6. Mount Batur, Bali

While it may not be the tallest, Mount Batur still presents real challenges as one of the most dangerous mountains in Indonesia. While the trail is relatively short and accessible, it is often described as slippery, steep, and dusty. 

Hiking to any of these most dangerous mountains in Indonesia truly tests a hiker’s determination while also rewarding them with unforgettable views. Ensure you have the proper gear, check volcanic activity updates, and consider hiring local guides who know the terrain.
