About this tour
This 22-hour trek departs Bali for Mount Ijen on Java's easternmost point, where you'll climb through darkness to witness the crater's ethereal blue sulphur flames at dawn. The journey includes return ferry crossings, a guided ascent with safety gear, and breakfast after descending. A medical clearance from a doctor is mandatory before departure, confirming fitness for the strenuous hike. The trek suits those with moderate-to-good fitness; it's unsuitable for pregnant travellers or those with spinal or cardiovascular concerns.
Highlights

- Safety equipment and experienced local guide provided

What to expect
You'll be collected from your Bali hotel in darkness for the ferry to Java—allow 7 hours for the crossing and onward drive. The actual climb takes roughly 2–3 hours uphill on steep, rocky terrain in near-total darkness with your torchlight and guide. You'll reach the crater rim as dawn breaks, revealing the blue flames and vast crater bowl. The descent mirrors the climb. Expect cold temperatures at altitude, strong sulphur smell, and physical exertion. Facilities are minimal; bring layers and water.
Good to know
Obtain a doctor's certificate of fitness within one day before the trek—this is non-negotiable. Wear sturdy hiking boots and bring a torch. The full 22 hours includes travel; actual trekking is roughly 5–6 hours. Not suitable for those with back problems, pregnancy, or weak cardiovascular health.
