IJEN DISCOVERY TOUR - KAWAH IJEN, BANYUWANGI

Kawah Ijen
The volcanic cone of Ijen dominates the landscape at the eastern end of Java. The Kawah or crater of Ijen is filled by a spectacular turquoise blue lake, its surface streaked in wind-blown patterns of yellow sulphur.

Almost sheer walls of white rock surround the lake, except where the wall has collapsed in the northwest. A dam has been built here to regulate the flow of water into Banyu Pahit river. The lake has been known to boil over when volcanic activity increases. A volcano logy post at Ungkup-Ungkup monitors volcanic activity all year round.
