Jakarta, Indonesia Sentinel — Mount Ijen, an active volcano on the border of Banyuwangi and Bondowoso in East Java, Indonesia, is home to the rare and mesmerizing blue fire phenomenon, one of only two such occurrences in the world. This natural wonder has turned the Ijen Crater into a major attraction, luring travelers willing to endure a challenging nighttime trek for the chance to witness the ethereal blue flames.
Mount Ijen, an active volcano straddling the border between Banyuwangi and Bondowoso in East Java, stands at 2,443 meters above sea level. At its summit lies the Ijen Crater, renowned for its rare and captivating blue fire phenomenon, which serves as the volcano’s primary attraction.
The blue fire results from the combustion of sulfuric gases released by Ijen’s acidic crater lake, which is one of the largest of its kind. As the sulfuric gas rises and meets oxygen at the surface, it ignites and produces a distinct blue flame. The extreme heat—reaching temperatures of up to 600 degrees Celsius (1,112 degrees Fahrenheit)—enhances the vivid color, creating a striking contrast against the darkness of night.
According to CNBC Indonesia, first observed by locals in the 1950s, the blue flames have gained increasing attention in recent years, attracting visitors from across Indonesia and around the globe. Mount Ijen last erupted in 1999, but its allure has only grown, thanks to its unique geological features and otherworldly nighttime spectacle.

To experience the blue fire, visitors typically begin their trek from the Paltuding base camp in Banyuwangi. The hike covers a distance of approximately 3.8 to 4 kilometers (2.3 to 2.5 miles) and takes about two hours to reach the crater. Travelers usually start their climb late at night, as the flames are best viewed between 2:00 AM and 4:00 AM, when the contrast with the surrounding darkness makes the vibrant blue glow particularly striking.
Once at the crater, visitors are greeted by the enchanting blue fire, a phenomenon only found in two locations in the world. As reminder of the volcano’s active nature, so there will be thick sulfuric smoke could aroudn the crater.
