We finally reached Ijen Plateau from Bromo Tengger Semeru National Park after an 8-hour tiring journey by bus. All of us were impressed by the amazing scenery on the mountain, where we stayed overnight.

It was amazing to witness the fresh sulfur stalactite shaping even though we made a big risk to suffer from the thick sulfur. Many local people make a living by trading them.

In fact, suffering from at least 8 hours of a tough journey, tourists flock to Ijen just for the miraculous electric-blue flame. The blue fire is ignited sulfuric gas, which emerges from cracks at temperatures up to 600 °C.

The flames can be up to five meters high; some of the gas condenses to liquid and is still ignited. It is the largest blue flame area in the world and local people refer to it as 'Blue Fire'.

It turned into a little bright when we stood on the top of the mountain. We were shocked to see such stunning lake view. 

The lake is recognised as the largest highly acidic crater lake in the world. It is also a source for the river Banyupahit, resulting in highly acidic and metal-enriched river water, which has a significant detrimental effect on the downstream river ecosystem.

A 2-hour hike is required to reach the rim of the crater, followed by a 45-minute hike down to the back of the crater.

We really had a good time together with two Poles, one Japanese on hiking and took a memorable photo when we had to say good bye to each other. 



We were waiting for bus for Denpasar, Bali in the front of local family and saw a child is playing by himself.



The Ketapang Port is connecting Ijen and Bali.
