When is the Right Time to See the Blue Flames at Ijen Crater?


Ijen Crater is an acidic crater lake that sits at the top of Mount Ijen with a lake depth of 200 meters.

Every morning around 02.00 to 04.00, around the crater you can find the phenomenon of blue fire, which is unique in this place.

Not only a crater lake, Ijen Crater is also one of the largest acidic craters in the world. This crater has a very high acidity level, which is close to zero so that it can dissolve the human body quickly.

Best Time to See Blue Flames 

The best time to visit Mount Ijen is during the dry season from July to September. In the rainy season it is very dangerous to climb because the roads are slippery. The best time to climb the mountain is from 05,000 to 06.00 WIB because in the morning the sun is not hot yet and the journey to go up and down the mountain is around four hours. The scenery in the morning is more beautiful because there is a lot of fog that covers the mountains and the sulfur vapor has not smelled.

Blue flames can only be seen in the early morning at Ijen Crater, which is at 01.00-02.00, before sunrise. The peak of the moment of beauty of Ijen Crater lies when the sun is in the other hemisphere. This bright color comes from the high temperature in the crater.
