You wake before the stars and walk into a wind that has been shaping Lombok's backbone for millennia.

By the time the ridge opens, the crater lake—Segara Anak—lies like a green bowl daring you to descend.

Acclimatize before summit day
Spend the first full day moving at a steady pace and sleep lower if possible; the summit reaches 3,726 m and altitude can hit hard.
Hydration and electrolytes
Carry at least 3 liters and a way to top up or treat water—high effort and dry wind increase fluid needs.
Guard your food from macaques
Long-tailed macaques are bold around camps—store food in packs and don’t eat in tents to avoid theft and conflict.
Start summit push very early
Summit hikes begin pre-dawn to reach sunrise and avoid afternoon storms; a headlamp and warm layers are non-negotiable.
Sturdy hiking boots
Support and traction for steep, rocky and sandy volcanic slopes.
Insulated sleeping bag (0°C to -5°C rating)
Night temperatures on the rim and at the summit can approach freezing.
Headlamp with extra batteries
Early starts and camp tasks require reliable hands-free lighting.
Lightweight trekking poles
Help protect knees on long descents and steady you on scree and sand.
