Mount Rinjani Opens in April – Trekking Season 2026
Located on the beautiful island of Lombok, Mount Rinjani is one of the most spectacular volcanoes in Southeast Asia and the third-highest mountain in Indonesia, standing at 3,726 meters above sea level. Every year thousands of trekkers from around the world visit this iconic mountain for its breathtaking landscapes, sunrise views, and the stunning crater lake Segara Anak.
Annual Closure Period
Each year, trekking activities in Mount Rinjani National Park are temporarily closed from January to March. This closure happens during the peak rainy season in Lombok, when heavy rainfall, landslides, slippery trails, and strong winds make trekking unsafe for visitors.
The closure also gives nature time to recover from the heavy tourist activity of the previous season while park authorities repair trails and improve trekking facilities.

The official trekking season for 2026 is expected to reopen on April 1, 2026 after the three-month closure period. From this date, all major trekking routes such as Sembalun, Senaru, and Torean are scheduled to operate again for hikers and adventure travelers.
April marks the beginning of the new trekking season, when the mountain landscape is still fresh and green after the rainy season, offering beautiful scenery and fewer crowds compared to the peak months.
