East Java’s Volcanic Wonders, Mount Ijen and Its Blue Fire Phenomenon
The Blue Fire Phenomenon
One of the main attractions of Mount Ijen is its rare blue fire, a natural occurrence caused by the combustion of sulfuric gases when they come into contact with oxygen at high temperatures. This phenomenon is best seen at night, making a pre-dawn trek necessary for those who want to experience its full beauty. Ijen’s blue fire is one of only two known places in the world where this phenomenon can be observed, the other being in Iceland.
The Best Time to Visit
The ideal time to visit Mount Ijen is during the dry season, from April to October, when weather conditions are more stable and the trails are safer. For the best experience, visitors should begin their hike around midnight or early morning (12:00 AM – 2:00 AM) to witness the blue fire before sunrise. The trek usually takes around 1.5 to 2 hours to reach the crater rim, followed by a steep descent into the crater to see the fire up close.
Essential Preparations for the Trek
Hiking Mount Ijen requires proper preparation due to the challenging terrain and exposure to sulfuric gases. Gas mask, the fumes from the crater can be intense, and a gas mask is necessary for protection. Headlamp or flashlight, the hike takes place in the dark, making proper lighting essential. Warm clothing, the temperature can drop significantly, especially before sunrise. Good hiking shoes, the trail is steep and rocky, so sturdy footwear is crucial. Water and snacks, there are no food stalls along the way, so it’s best to bring your own.
The Sulfur Miners, a Tough but Vital Livelihood
For many locals, Mount Ijen is more than just a tourist attraction; it is their workplace. Sulfur mining is the primary source of income for many residents. Miners carry heavy baskets of solid sulfur weighing up to 70–90 kg per trip, enduring the harsh conditions of the crater. Despite the dangers, this job remains one of the main livelihoods for the surrounding communities, showcasing their resilience and hard work.
Facts About Mount Ijen
Mount Ijen’s crater lake is the largest acidic lake in the world, with a pH level close to zero, making it highly corrosive. The stunning turquoise color of the lake is caused by dissolved metals and extreme acidity. Due to safety concerns, visitors are sometimes restricted from entering the crater if gas levels are too high.
Places to Stay Before Hiking
Since the hike to Mount Ijen begins around midnight, choosing the right accommodation is crucial for a comfortable rest before the trek. For those who want to stay closer to the hiking entrance, there are small homestays available near the basecamp. These homestays are simple and modest, offering basic facilities for travelers who prioritize proximity over luxury. They provide a practical option for those who want to minimize travel time before starting the hike.
