The Largest Acidic Lake in the World
At the heart of Kawah Ijen lies a mesmerizing turquoise-blue lake, spanning 1 kilometer in diameter and reaching depths of up to 200 meters. This lake is renowned for being the largest acidic lake in the world, with pH levels so low that its waters are highly corrosive. The sulfuric acid in the lake gives it a unique, striking color that contrasts beautifully against the surrounding rugged volcanic landscape.

From the rim of the crater, visitors are treated to an awe-inspiring view of the lake, which seems to shimmer in the early morning light. The serene appearance of the lake, however, hides its volatile nature. The sulfurous fumes rising from the lake create an almost mystical atmosphere, but they also remind travelers to exercise caution due to the lake's extreme acidity.
The Blue Flames of Ijen
One of Kawah Ijen’s most iconic and rare phenomena is the mesmerizing “blue flames” that appear in the dark. These flames are a result of the combustion of sulfuric gases, which emerge from the cracks in the volcano’s surface. When the gases come into contact with oxygen and ignite, they produce a vivid blue glow that is both eerie and beautiful.
