About this tour
A guided hike to Ijen volcano on Java to witness the rare blue flames produced by burning sulphur gas. Departs from Bali early morning and includes private transport, permits, breakfast, and a gas mask. Suited to fit, adventurous travellers seeking a distinctive natural phenomenon rather than a casual walk — this is a moderately strenuous trek in volcanic terrain starting before dawn.
Highlights
- Witness electric-blue sulphur flames erupting from volcanic cracks at night
- Private transport and pickup from your Bali hotel included
- Experienced trekking guide accompanies you throughout
- Gas mask and all permits provided
- Early-morning start to catch flames before sunrise fades them
- Breakfast included before the hike begins
- Pre-trek medical check-up for your safety
What to expect
You'll be collected from your Bali hotel in an air-conditioned vehicle for the drive to Ijen on Java. A medical check-up happens before you start. The trek begins very early, usually around 1–2 a.m., so you can reach the crater rim as the blue flames are most visible — typically between 3–5 a.m. Your guide leads you uphill through dark volcanic landscape wearing the provided gas mask to protect against sulphur fumes. You'll spend time at the crater observing the flames and the wider caldera landscape as daylight breaks. The descent and return to your hotel takes the afternoon.

Good to know
This suits adventurous, reasonably fit travellers wanting something beyond typical beach tourism. It's not suitable for anyone with spinal issues, pregnant travellers, or poor cardiovascular health — the terrain is uneven and the climb sustained. The very early start (often midnight departure) is non-negotiable. High altitude, volcanic gases, and cold mountain air are part of the experience. Breakfast is included; bring your own snacks and water. Group size varies. Not pram-friendly; infants must be held. Wear sturdy hiking boots and warm layers — the pre-dawn mountain air is cold despite Bali's tropical climate.
