Ijen is a volcanic complex at the eastern end of the Indonesian main island of Java. It is particularly famous for its blue sulphur flames and the turquoise volcanic lake, Kawah Ijen. One thing in advance: You can do the Ijen even without a certain basic athleticism. Just don’t have a problem getting up early if you want to see the flames in the dark. A visit to Kawah Ijen can be ideally combined with a holiday in Bali or with a trip to Java from Bali or vice versa. The ferry to Bali (larger island at the bottom right of the picture) takes less than an hour. The starting point for Ijen is the town of Banyuwangi. It is a good idea to combine Ijen and Bromo, as they are easily accessible by train. Be sure to check if Ijen is open before you arrive, as it closes sporadically when volcanic activity is too high.<\/p>\n\n\n\n Crater lake<\/strong><\/p>\n\n\n\n Kawa Ijen captivates with its turquoise water and rising vapours. The lake itself is also called the “largest acid barrel on earth”. The lake is almost 1 km long, 600 m wide and up to 200 m deep. The PH value of the lake is 0.3 in some places – that’s just sick, considering that even battery acid has a PH value of about 1. Logically, this means there is no life at all in Kawah Ijen.<\/p>\n\n\n\n![\"\"](\"https:\/\/travelsloth.de\/wp-content\/uploads\/2021\/01\/Kaw_Ijen.jpg\")
