The magma chambers beneath the volcano push sulfuric into the lake bed, which combines with dissolved metals in high concentrations, resulting in gas in the lake that turns the water blue. Besides, the above process also makes Kawah Ijen crater the most acidic lake in the world with a pH of 0.5. (Photo: Vntravellive) The best time to visit Indonesia’s unique volcano is between April and October, because this is the dry season, so the weather is relatively favorable for climbing journeys.

In addition to the magical blue fire, this Ijen volcanic complex also holds another “dark secret” because this is one of the largest and most dangerous sulfur mining places in the world.

Although the work is hard and adversely affects health, these miners are not equipped with any protective gear, even they have to take dangerous shortcuts to ensure their safety. most trips per day. Thanks to the increasing number of tourists visiting the Kawah Ijen volcano, the miners have found a way to supplement their income by selling sulfur drawings and ornaments for as little as $1.74 per month. each item.
