About this tour
Trek to Mount Ijen's crater to witness the rare blue flames of burning sulphur gas—a geological phenomenon few travellers experience. This two-day overnight adventure from Bali includes hotel pickup, a local guide, meals, and accommodation in Java. You'll hike to the volcano's rim in darkness to catch the ethereal glow before sunrise, then descend via a working sulphur mine and stop at a local coffee plantation to recover.
Highlights
- Watch electric-blue sulphur flames ignite at the crater rim
- Hike through darkness with headtorch to catch pre-dawn glow
- Local guide navigates volcanic terrain and safety protocols
- Visit active sulphur mining operation on descent
- Rest at traditional coffee farm between hike sections
- All transport, meals, and overnight stay arranged
What to expect
You'll be collected before dawn and driven to the trailhead. The three-hour uphill trek begins in darkness—your guide leads you across volcanic rock and sulfurous air pockets to the crater rim. The blue flames appear most vivid before sunrise, creating an otherworldly scene against the black landscape. After witnessing this, you'll descend into the crater itself, passing workers who hand-mine sulphur deposits using basic tools. The descent takes longer than the ascent. A coffee plantation visit halfway down offers a chance to sit, eat breakfast, and let your legs recover. You'll return to your accommodation by mid-morning.
Good to know
Moderate to strong fitness required—the hike is steep and the sulphurous air can irritate lungs. A respiratory mask is provided. Wear sturdy hiking boots and layers; the crater is cold and windy at night. Minimum age 15; not suitable for those with spinal or serious heart conditions. Bring a headtorch with fresh batteries.
