2. The Phenomenon of Blue Flames

One of the most striking features of Kawah Ijen is its blue flames, a rare natural phenomenon caused by the combustion of sulfuric gases. These gases emerge from cracks in the earth and ignite upon contact with oxygen, creating vivid blue flames that can reach up to 5 meters in height. The best time to witness this phenomenon is between 2:00 AM and 4:00 AM, as the surrounding darkness enhances the visibility of the flames.

3. Sulfur Mining at Kawah Ijen

Kawah Ijen is also home to sulfur miners who extract sulfur directly from the crater. These miners work in hazardous conditions, carrying heavy loads of sulfur up and down the steep slopes. Their resilience and determination are a testament to the harsh realities of their profession. The sulfur extracted is used in various industries, including chemicals and pharmaceuticals.

4. The Acidic Crater Lake

At the base of Kawah Ijen lies a turquoise-colored acidic lake. The lake's acidity is so high that it can dissolve metal and poses significant risks to human skin. The lake's unique color is due to the high concentration of sulfuric acid, which also contributes to the formation of sulfur deposits around the crater.
