- Direct access to the summit in a shorter distance.

The Trekking Itinerary from Sembalun
Day 1: Arrival and Trek to Sembalun Crater Rim
- Starting Point: Sembalun Village (1,150m)
- Destination: Sembalun Crater Rim (2,639m)
- Duration: 6–8 hours
The journey begins with registration at the Rinjani Information Center in Sembalun. From here, the trail winds through open savannas, offering wide landscapes but limited shade. After several rest posts, trekkers finally reach the Sembalun Crater Rim, where campsites provide spectacular views over Segara Anak Lake and the summit ridge.
At night, trekkers enjoy sunset views over Lombok’s northern coastline, making this one of the most magical camping spots on the mountain.
Day 2: Summit Attempt and Descent to Lake
- Starting Point: Sembalun Crater Rim (2,639m)
- Destination: Mount Rinjani Summit (3,726m) and Segara Anak Lake (2,000m)
- Duration: 8–10 hours
The summit climb begins around 2:00 AM, allowing trekkers to reach the peak by sunrise. The trail is steep, sandy, and demanding, often described as “two steps up, one step down.” However, the reward is unparalleled — a 360-degree panorama over Lombok, Bali’s Mount Agung, and even Sumbawa in the distance.
After enjoying the breathtaking sunrise, trekkers descend back to the crater rim for breakfast before continuing to Segara Anak Lake. This turquoise volcanic lake is surrounded by dramatic cliffs and hosts natural hot springs, perfect for soothing tired muscles.
Day 3: Return Journey via Senaru or Sembalun
- Option 1: Return to Sembalun Village (shorter and direct).
- Option 2: Continue through the Senaru Route, exploring dense tropical forests before descending to Senaru Village.
Most trekkers choose the Sembalun–Senaru combination, offering the chance to experience both landscapes: open savannas and lush forests.

Difficulty Level and Physical Preparation
While the Sembalun route is shorter, it remains physically demanding. Trekkers face:
- Long walking days of 6–10 hours.
- High altitude and thinner oxygen near the summit.
- Loose volcanic sand making ascents challenging.
We recommend preparing with cardio training, endurance hikes, and strength exercises at least a month before the trek. Acclimatization is also key to reducing the risk of altitude sickness.

The ideal trekking season is during the dry months from April to December. During this period:
- Trails are safer and more accessible.

- Campsites are comfortable and scenic.
The rainy season (January–March) is usually closed for trekking due to safety hazards such as landslides and slippery trails.
