Gua Upas or Gua Jimat, Cave located in Dieng Plateau

Though it is called as gua or cave, but actually it is a dead crater, and in certain time the crater expels poisonous (upas) gas which can not be seen and can not be smelled. This gas can jeopardize human life. That is why this crater also is called as death valley. In this area located the grave of Herman Keller, a German man who died in 1883 for approaching the cave.
Jimat derives from local people believe that this cave has many invisible amulets owned by gods and now guarded by genies. Whoever want to get an amulet should meditate here.
