What Makes Kawah Ijen So Special?

1. The Acidic Crater Lake
At the top of Mount Ijen lies a massive acidic lake with a diameter of 722 meters and an area of 0.41 square kilometers. According to the Smithsonian’s Global Volcanism Program, it’s the largest acidic lake on Earth, with pH levels ranging from 0.5 to as low as 0.13.
Of course, it’s not safe to touch or swim in—but it’s absolutely beautiful to look at. The blue-green gradient of the water is mesmerizing, and the surrounding cliffs make the view even more dramatic. You’ll also find solfataras, areas of active sulfur vents with bright yellow sulfur deposits.
These vents are the heart of Ijen’s sulfur mining activity. Here, miners extract molten sulfur that later hardens into stalactite-like formations on the rock walls. It’s hard, physical labor carried out by foot under tough conditions.

2. The Eternal Blue Flame
While the band The Bangles sang about an “Eternal Flame,” Kawah Ijen Banyuwangi boasts something even more magical: the Eternal Blue Flame.
To see this phenomenon, you’ll need to start your hike at night. Yes, it’s a bit of a trek, especially with the rocky terrain—but it’s worth every step. Once you reach the solfatara area under the starry sky, you’ll see something surreal: flickering blue and violet flames rising from cracks in the earth. These flames are caused by sulfuric gas combusting as it escapes from the ground.
The flames can leap up to 5 meters high, with temperatures reaching 600°C. You might even catch glimpses of orange fire mixed in. It’s a once-in-a-lifetime view. But be sure to keep a safe distance. Your safety always comes first.
3. The Sulfur River
Another highlight of Ijen’s nightscape is the glowing sulfur river. As temperatures drop, some of the sulfur gas condenses into liquid and flows along the crater’s surface like lava, glowing faintly blue in the dark. It’s a scene straight out of a fantasy film.

Kawah Ijen is located on Mount Ijen, straddling the Banyuwangi and Bondowoso regencies. How high is Mount Ijen? It has an elevation of approximately 2,799 meters (9,186 feet) above sea level
How to get to Mount Ijen? To get there, head to Paltuding Post, about 64 kilometers from Bondowoso city center. This post marks the official start of the hiking trail—and the border between the two regencies.
How long to climb Mount Ijen? Climbing Mount Ijen typically takes about 1.5 to 2 hours to reach the crater rim from the base, covering a distance of roughly 3.5 kilometers uphill on a steep and sometimes slippery trail. After reaching the rim, if you want to see the famous blue fire at the bottom of the crater, it takes an additional 25 to 45 minutes descending into the caldera and then climbing back up.
The full experience, from the parking lot to the crater rim, descent to the blue fire, and return, usually takes around 4.5 to 6 hours, depending on your fitness and pace. The trail is moderate to challenging due to the steep pitch and rocky terrain. It is usually done at night or very early morning to catch the blue fire and the sunrise.
Kawah Ijen Entry Ticket Price
To access the crater, you’ll need to buy an entrance ticket:
- Indonesian visitors: Rp20,000 (weekdays), Rp30,000 (weekends)
- Foreign visitors: Rp150,000 (daily)
Tickets are sold at the Paltuding gate, which opens at 1 AM and closes at noon. That’s because the blue fire is only visible at night and fades as daylight approaches. So make sure to arrive early!
Once you’ve seen the blue flames, stay a bit longer to catch the sunrise. The soft mix of orange and blue over the lake and cliffs creates a peaceful and unforgettable morning moment. What a way to start your day!
