A concentrated, two-day guided trek from Sembalun to Rinjani’s summit and rim. Expect steep gains, loose volcanic scree, an overnight rim camp, and sunrise views over Segara Anak.
More ways to explore the area's outdoor wonders
You step out of the pre-dawn cold in Sembalun, lanterns blinking on tents, and the mountain already filling the horizon like a dark promise. The first day unfolds along grassy slopes that give way to volcanic scree; the crater rim sits above a wide bowl and the wind feels like a hand nudging you onward. At night, the stars and a distant glow from the caldera make camp a brief, alpine theatre.

Acclimatize in Senaru or Sembalun before ascent
Spend a day at low elevation if you’ve arrived from sea level to reduce acute altitude effects before the summit push.
Carry extra water and high-calorie snacks
Hydration and quick-energy foods are essential on the second-day ascent when oxygen and appetite fall short of demand.
Use local guides and porters
Guides manage permits, route-finding and camp logistics—hire them to reduce risk and support the local economy.
Watch for loose volcanic scree near the summit
Descents on scree can be fast and unstable—use poles and controlled steps to avoid slips.
Sturdy waterproof hiking boots
Provide ankle support and traction on loose volcanic rock.
Insulating layers and wind shell
Temperatures drop sharply at the rim—layering manages heat and wind-chill.
Headlamp with extra batteries
Summit bids start pre-dawn; hands-free light is essential.
Trekking poles
Stabilize descents on scree and reduce knee strain over long downhill stretches.
