Rising 3,726 meters above sea level, it is the second-highest volcano in Indonesia and one of the most famous trekking spots in Southeast Asia. Whether you are an experienced mountaineer or a beginner adventurer seeking a once-in-a-lifetime challenge, hiking Mount Rinjani in Indonesia will give you an unforgettable journey filled with breathtaking landscapes, cultural encounters, and spiritual meaning.
In this detailed guide, we’ll cover everything you need to know about climbing Mount Rinjani, from the history and cultural significance of the volcano to practical trekking tips, routes, and preparation.
1. Introduction to Mount Rinjani
Mount Rinjani stands on Lombok Island in West Nusa Tenggara, Indonesia. This majestic stratovolcano dominates the skyline and forms the heart of Mount Rinjani National Park, a UNESCO-recognized geopark known for its rich biodiversity and stunning scenery.
The mountain is especially famous for Segara Anak, a turquoise crater lake inside the caldera. Around the lake lies an active volcanic cone called Gunung Barujari, which still emits smoke and occasional lava flows, making Rinjani a living geological wonder.
For both locals and visitors, Rinjani is not just a trekking destination but also a place of spiritual importance. Balinese Hindus and the Sasak people often make pilgrimages to the lake and crater, performing rituals to honor the gods and spirits believed to inhabit the volcano.
2. Why Hike Mount Rinjani?

- Spectacular landscapes: From lush tropical forests to barren volcanic terrain, the scenery changes dramatically as you ascend.
- The Crater Lake (Segara Anak): A surreal sight, with a deep blue lake framed by volcanic ridges.
- Sunrise from the summit: One of the most rewarding views in Indonesia, offering panoramas of Lombok, Bali, and even Sumbawa.

- Dry season (April–November): Best conditions, with warm days and cooler nights.

4. Popular Trekking Routes
Mount Rinjani offers several trekking routes, but the two most popular are Sembalun and Senaru.

5. Trekking Itineraries
The length of your trek depends on your fitness level and the experience you want.
