Mt Ijen, Indonesia and the quest for the blue fire, as the locals call it. Watch to discover Mt Ijen and it's sulphuric fumes, sulfur-collecting workers, acidic lake, and blue fires. This volcano will probably be one of the most interesting places you've ever been. You can hike Mt Ijen without a guide, even though everyone will tell you that you can't. It's better without one, and it's cheap.
