Kawah Ijen is an active stratovolcano in East Java. It is famous for its blue fire phenomenon. Sulfuric gases escape from cracks and ignite at extreme temperatures. You can only see these flames in complete darkness.
The crater holds a turquoise lake with a pH level below 0.5. It is the most acidic crater lake in the world. The site operates as a working sulfur mine. Miners carry heavy loads of yellow sulfur up the steep walls manually.
Hikers start at Paltuding basecamp. The trail climbs 600 meters over 3.5 kilometers. You must bring a gas mask and a health certificate to enter. Read Trail Difficulty for details on the physical demands.

The guides were phenomenal. The views were incredible. Highly recommend.
The kids were amazed by the Blue Fire! The trek was moderately challenging, but the views of the crater lake made it worth it. Good Feelings Adventure planned the route and schedule professionally, allowing us to enjoy the family experience fully. Meeting local sulfur miners added a meaningful cultural aspect that made the trip unforgettable!
Just perfect ! Andre did the best for making the most beautifull pictures ! ❤️

He looked after us the entire way and made sure we got to all the best spots and views. Such an incredible experience and we couldn’t have asked for a better guide. Thank you Lucky! ❤️
I was with Ray, my local tour guide for three days on this tour and he and the local guides who took care of me on location always did the extra mile. So many unforgettable experiences, so many new friends on the way, so many beautiful and exciting places and things to see. Thank you very much, 11/10!
Superb experience, we loved our 3-day, 2-night stay. Our guide Ray was fantastic and really helped us enjoy the best spots in Bromo and Ijen.

Amazing experience in the heart of the volcanoes! 🌋 The traditional food was absolutely delicious, and the people were incredibly kind and welcoming. Such a beautiful and authentic experience ! highly recommend!
This was an incredible hike, the surrounding nature is beautiful, and our guide took such great care of us, especially where the path seemed a little dangerous. He took photos for us, told us stories and even made a short video at the end. The crowd was larger than expected. An incredible experience and tour guide we highly recommend to anyone visiting Indonesia :)
