Mount Rinjani
Mount Rinjani (3,726m) is Indonesia's second highest volcano and one of Southeast Asia's most spectacular trekking destinations. Located in Lombok, the mountain offers breathtaking views of the crater lake Segara Anak, the Lombok Strait, and on clear days, Bali's Mount Agung.
The trek to the summit is challenging but deeply rewarding. The most popular routes depart from Senaru in the north or Sembalun in the east, with multi-day options ranging from 2 to 4 days. The crater lake sits at 2,000 metres and is considered sacred by the Sasak people of Lombok, who make pilgrimages here annually.
Guided treks are mandatory in Rinjani National Park, ensuring both visitor safety and environmental protection. Certified guides and well-established camps make this accessible to fit, determined trekkers even without mountaineering experience.
