Dubbed as the “Giant Acid Bowl,” Kwah Ljen Lake in Indonesia has become a sought-after destination for many travelers, thanks to its breathtaking natural scenery and a hint of mystery behind its impressive beauty.
Kwah Ljen Lake – The Enigmatic Giant Acid Bowl in Indonesia with Emerald Green Hue
Kawah Ljen Lake is situated in the volcanic area of Ljen, nestled between the Bondowoso and Banyuwangi plateaus (eastern Java, Indonesia). The lake sits 2,300m above sea level, with a diameter of approximately 361m and a depth of 200m. Together with its neighboring areas, Kawah Ljen Lake forms a vast volcanic lake complex spanning 45 hectares.

What sets this body of water apart is its immense reservoir of 36 million cubic meters of acidic water, famously known as the “Giant Acid Bowl.” The lake’s surface boasts a mesmerizing emerald green color, complemented by dense white smoke that adds a mystical, ethereal ambiance.



Moreover, the air here often carries the pungent smell of rotten eggs due to sulfur compounds, as the lake area hosts a massive sulfur mine. According to scientists, the lake has a pH level equivalent to that of battery acid. Many refer to this place as the “Lake of Death” due to its inherent dangers and harsh conditions. During the day, sulfur typically appears as solid reddish-yellow deposits. But as night falls, sulfur gas ignites, emitting a neon blue glow. Amidst the eerie darkness, the luminous blue light creates a surreal, otherworldly beauty atop the Ljen volcano.




The beauty of this place can be described as nearly year-round stunning. No matter the time of day, visitors are treated to various unique and impressive sights. However, tourists should limit their time here to avoid inhaling excessive sulfur fumes, which can cause discomfort and difficulty breathing.
