About this tour
This 24-hour expedition from Bali takes you to Java's Kawah Ijen volcano to witness the otherworldly blue flames at night, then watch sunrise over the world's largest acidic crater lake. You'll depart Bali in the early afternoon, enjoy a local dinner, sleep in a comfortable room, then climb to 2,370 metres for the pre-dawn hike into the active crater. Your guide handles navigation and shares insights into the geology and sulfur-mining operations that sustain the local community. Transport, accommodation, meals, and all technical gear are bundled in.
Highlights
- Night ascent to summit and crater rim for blue flame viewing
- Guided descent into active volcanic crater at altitude
- Sunrise over the largest acidic lake on Earth
- Meet sulfur porters and witness their daily work
- Hot shower and rest in private room post-hike
- Bali-Java ferry and all transport included
What to expect
You'll leave Bali at 1 PM and drive to East Java, arriving in time for a vegetarian or halal dinner before settling into your private room. Sleep well—the real work starts before dawn. Your guide will wake you for the night hike to the crater rim, a steady uphill trek where a gas mask, torch, and gloves become essential. The blue flames are brief but striking, visible as sulphur ignites. You'll also see porters hauling heavy sulfur loads in challenging conditions. After descending and resting, breakfast follows before your return journey to Bali.
Good to know
Moderate fitness required; children under 10 need special approval and adult supervision. Hotel pickups in Bali aren't included—arrange your own transport to the departure point. Bring tips for guides and drivers. Travel insurance isn't covered. The air quality around the crater can be harsh; the gas mask is non-negotiable.
