Mount Ijen: Guide to Indonesia’s Blue Fire Volcano Adventure

Mount Ijen is a special volcano in East Java, Indonesia. It is famous for its bright blue fire, a colourful acidic crater lake, and the hardworking sulphur miners who work there every day. Climbing Mount Ijen is not just about seeing great views — it’s about experiencing the power of nature and the strength of people. If you are visiting Indonesia, Mount Ijen should be on your list.

About Mount Ijen

Mount Ijen is in East Java, between two areas called Banyuwangi and Bondowoso. It is part of a group of volcanoes, and its crater is called Kawah Ijen. This crater is famous for the glowing blue fire and a big, bright turquoise lake filled with very strong acid.

The mountain is about 2,799 metres (9,183 feet) tall, making it a tall and beautiful place to explore.

The Blue Fire

The blue fire at Mount Ijen is a very rare and amazing sight. It happens when sulphur gas comes out from cracks in the volcano and catches fire when it meets the air. This fire burns bright blue, but you can only see it in complete darkness.

The best time to see the blue fire is between 1:00 AM and 4:00 AM. The fire is not like a normal flame made from wood — it is burning gas from the sulphur and gets very hot, over 600°C (1,100°F).

Mount Ijen is one of only two places in the world where you can see this blue fire, so it is very special. Learn more about the phenomenon on National Geographic.

The Acidic Crater Lake

When the sun rises and the blue fire disappears, you will see a bright turquoise lake inside the crater. This lake is very beautiful but also very dangerous because it is full of acid. The lake is the largest acidic lake in the world, with a pH level close to zero (which means very strong acid).

The colour of the lake comes from minerals and sulphur in the water. It is important to stay far away from the lake and always wear a gas mask to protect yourself from strong sulphur smells.

The Sulphur Miners

One of the most impressive things at Mount Ijen is the sulphur miners. These workers go down into the crater every day to mine solid sulphur. They use simple tools to break the sulphur and carry heavy loads — sometimes up to 80 kilograms (176 pounds) — up the steep mountain path.

Their work is very hard and dangerous because of the poisonous gases and heavy weight. Watching them is both inspiring and humbling. If you want, you can support them by giving a small tip. Read more about the miners’ lives in this BBC article.

How to Get to Mount Ijen

It is not difficult to get to Mount Ijen. Here are the main ways:

• From Banyuwangi: This town is the closest to the basecamp at Paltuding, about 1.5 hours by car.

• From Bali: Take a ferry from Gilimanuk (Bali) to Ketapang (Banyuwangi), then drive to Paltuding.

The Hike to the Crater

The hike starts at Paltuding, around 1,850 metres above sea level. The trail is about 3 kilometres long and usually takes 1.5 to 2 hours, depending on how fit you are.

The path is steep and rocky in some places, so wear good shoes. It can be cold, especially before sunrise or at night.

If you want to see the blue fire, you will need to start hiking around midnight. Bring a torch or headlamp and warm clothes.

To have a safe and comfortable hike, bring:

• Warm clothes (it can get as cold as 5°C at night)

• Comfortable shoes for hiking

• A gas mask (most tours provide this)

• A torch or headlamp

• Snacks and water

Best Time to Visit

The best time to visit Mount Ijen is during the dry season from April to October. The trails are safer and the weather is clearer then.

The rainy season from November to March can make the path slippery and the view cloudy.

Try to visit on weekdays and avoid Indonesian holidays if you want fewer people.
