About this tour
Chase the electric-blue sulphur flames at Mount Ijen's crater, departing Bali at dusk for a pre-dawn trek across Java. You'll cross by ferry to Banyuwangi, climb through darkness with a guide and gas mask, and arrive as the phenomenon ignites around 4 AM—a geological oddity where combustible gases burn brilliant blue against the black volcano. Watch the display fade with sunrise, descend by mid-morning, and return to Bali by early afternoon. Total journey runs 5–7 hours on foot and vehicle combined.

What to expect
You'll be picked up in Bali at 7 PM and driven to the ferry port, then cross to Java's Banyuwangi port around midnight. After a half-hour drive inland, the trek begins at Paltuding around 2 AM—steep, rocky, and unlit except for your torch and guide's knowledge. The climb takes roughly two hours; expect loose volcanic scree, cold air, and moderate exertion. The blue flames appear around 4 AM as sulphur vents ignite; they're real but subtle in darkness and cease at first light. You'll descend by 7 AM, stop for a local breakfast (not included), and be back in Bali by 12:30 PM.
Good to know
Bring sturdy hiking boots, warm layers, and a torch. The trek suits moderate fitness only; spinal injuries, pregnancy, and poor heart health aren't compatible. Mount Ijen closes the first Friday of each month. Note: blue flames are occasionally obscured by weather or natural conditions. Ferry and vehicle times run to schedule; delays are rare but possible.
