Dawn breaks over the Sembalun plain and the mountain breathes a cold, sharp air that pushes through tall grasses as you begin the climb. On day one the trail rises from 1,156 m through rolling grasslands to the Sembalun crater rim (2,639 m), where the island drops away and Lake Segara Anak sits like an inland sea, steam rising from its hot springs.

Acclimatize before the summit
Spend the first night at the crater rim (2,639 m) and avoid pushing too hard on day two; the early morning summit ascent is steep and cold.
Hydration and electrolytes
Carry at least 3 liters of water per day and use electrolyte tablets—altitude and exertion increase dehydration risk.
Footwear and poles
Sturdy, broken-in hiking boots and trekking poles are useful on loose pumice and steep descents to protect knees and improve balance.
Protect against sun and cold
Bring a sun hat and high-SPF sunscreen for daytime exposure and a warm insulated jacket for summit winds and nights in camp.
Sturdy hiking boots
Support and traction on loose pumice, steep slopes and rocky trails.
Insulated jacket and warm layers
Summit and nights are cold—warm layers prevent hypothermia during wind and pre-dawn starts.
Headlamp with extra batteries
The summit push starts around 2:00–3:00 AM and reliable light is essential for safety.
Light waterproof shell
