Overnight Private Tour from Bali to Mount Ijen's Blue Flames

About this tour

A two-day overnight expedition from Bali to Mount Ijen, where you'll hike under stars to witness the mountain's famous blue sulphur flames and turquoise crater lake at dawn. Your local guide leads you through the darkness to catch this rare geological phenomenon, then you'll descend as daylight breaks over the crater. The trek also reveals the daily reality of sulphur miners working the volcanic slopes—a sobering glimpse into their labour and the landscape they navigate.

Highlights

• Blue sulphur flames visible only in darkness
• Turquoise crater lake at sunrise
• Night hike with headlamp and expert local guide
• Watch sulphur miners extract baskets from the crater
• Private transport, accommodation, meals included
• All safety gear and insurance provided

What to expect

You'll be collected from your Bali hotel in the evening and driven to Mount Ijen's base. The hike begins after midnight, ascending steep volcanic terrain with a headlamp and mask—the sulphur fumes require protection. Around 2–3 a.m., you'll reach the rim and witness the blue flames flickering across the crater floor, an ethereal sight caused by burning sulphur gases. As dawn approaches, the flames fade and the turquoise lake comes into view. You'll descend mid-morning, stopping to observe miners hauling sulphur loads along narrow paths. Lunch and hotel drop-off follow. Expect cold temperatures, challenging footing, and the physical demands of a steep nocturnal climb.

Good to know

This trek suits only moderate-to-fit travellers. Not suitable if pregnant, with spinal issues, or poor cardiovascular health. Wear sturdy boots and warm layers; the crater rim is cold and windy. The mask protects against sulphur—follow your guide's instructions. Start time is around midnight; check exact pickup with your operator.
