Why Is the Blue Fire Phenomenon at Mount Ijen Special?
The blue fire at Mount Ijen is a rare natural occurrence resulting from the combustion of sulfuric gases that emerge from cracks in the volcano at high temperatures.

To witness the blue fire, visitors must descend into the crater before sunrise, guided by experienced local miners or tour operators. The spectacle is best observed in total darkness, which is why the hike begins at night. It is important to note that due to the presence of toxic sulfur gases, wearing a gas mask is mandatory for safety.
