A two-day, one-night guided trek from Sembalun to Mount Rinjani’s 3,726 m summit, combining steep volcanic climbs, a crater-rim camp and a pre-dawn summit push for sunrise. Expect scree, long meadow crossings and panoramic island views.

Dawn on the Sembalun plain begins cool and blade-sharp; headlamps fade as a ribbon of hikers threads up stony switchbacks toward the crater rim. Day one climbs from roughly 1,150 m through sun-baked meadows and a series of five steep ridges to Pelawangan Sembalun at 2,639 m, where tents gather on the crater lip and Segara Anak Lake sits like a dark eye below.

History
Rinjani’s caldera formed in explosive eruptions; the inner Segara Anak Lake and small volcanic cone reflect the island’s active geological past and local Sasak sacred traditions.
Conservation
Rinjani National Park regulates trekking permits and limits camping to designated rims; stay on trails, pack out waste and use local guides to support sustainable access.

Acclimatize before ascent
Spend a day at a lower elevation or arrive in Senaru a day early to help reduce altitude sickness risk on the summit push.
Bring a reliable headlamp and spare batteries
The summit start is very early; a bright headlamp makes steep, rocky sections and pre-dawn moves safer.
Use trekking poles
Poles save knees on steep descents and help maintain balance on loose volcanic scree.
Hydrate and use electrolytes
Carry at least 2 liters and sip frequently—cold, dry altitude and exertion increase dehydration risk.
Sturdy waterproof hiking boots
Support and traction for long steeps, scree and wet sections.
Insulating mid-layer (down or synthetic jacket)
Summit temperatures can drop near freezing; warm mid-layers are critical pre-dawn.
winter
Lightweight waterproof shell
Protects against wind and sudden tropical showers, especially on the crater rim.
fall
Headlamp with spare batteries
Necessary for the pre-dawn summit ascent and early-morning camp tasks.
