Sembalun Trek route
The Sembalun route is one of the most popular trails for trekking Mount Rinjani in Indonesia. Starting at an altitude of 1,100 meters, this route offers open landscapes with rolling hills and breathtaking scenery, making the initial phase of the trek relatively enjoyable. Unlike the dense tropical rainforest of the Senaru route, the Sembalun trail provides wide, unobstructed views of the surrounding valleys and mountains, allowing trekkers to fully appreciate the natural beauty of the area.
As the trek progresses, the climb gradually becomes more challenging, especially from POS 2 to POS 3. The terrain consists of a mix of grassy slopes and rocky paths, requiring steady endurance. However, the open environment allows for better airflow, making the hike more comfortable despite the increasing elevation. Trekkers should stay hydrated to prevent altitude sickness, which can set in unexpectedly as they gain height.

However, reaching the crater rim at around 2,639 meters is a rewarding experience. Offering stunning panoramic views of Segara Anak Lake and the towering summit of Mount Rinjani. Many trekkers choose to camp here before attempting the summit the next morning, making the Sembalun route a scenic yet challenging adventure
