Ijen Blue Fire: Everything You Need to Know Before You Go

A Hidden Gem in East Java

In the mountains of East Java, there’s a rare natural wonder. It’s called the Ijen Blue Fire. This glowing blue flame, seen only at night, is caused by ignited sulfuric gas. It creates a surreal experience that draws adventurers from around the world.

In this guide, you’ll discover what the Ijen Crater Blue Fire is, how to see it, and what to expect when hiking Mount Ijen.

What Is the Blue Fire in Ijen Crater?

The blue fire phenomenon in Indonesia happens when sulfur gases escape from deep cracks in the earth. These gases ignite when they hit the air. The flames can reach up to 5 meters high.

This fire burns blue due to the high temperature, up to 600°C (1,112°F). It’s often mistaken for blue lava, but it’s burning gas, not molten rock.

You can read more about the science behind it on National Geographic.

Why Is Kawah Ijen Blue Fire Famous?

Kawah Ijen is one of only two places on Earth where you can see this fire. The other is in Iceland. But Mount Ijen Blue Fire is far more intense and visible.

Travelers love this spot not just for the flames. The Ijen Crater Lake, the sulfur miners, and the eerie nighttime hike make it unforgettable.

How to See Ijen Blue Fire

Seeing the natural blue fire Ijen is not as simple as showing up. It requires effort and timing.

Here’s how to do it:

• Join an Ijen Midnight Tour: Most tours start at midnight so you reach the crater before sunrise.

• Start the Hike at 1:00 AM: It takes 1.5 to 2 hours to reach the crater rim.

• Descend into the Crater: Another 30–45 minutes brings you close to the blue flames of Ijen Crater.

• Wear a Gas Mask: The sulfur smoke is strong and can be dangerous.

• Hire a Local Guide: This ensures safety and gives you more insight into the area.

Many travellers book a guided Ijen Blue Fire Tour from Bali, Banyuwangi, or Surabaya.

Best Time to See Ijen Blue Fire

The best time to see Ijen Blue Fire is during the dry season. That’s from May to October.

Here are a few tips:

• Avoid cloudy or rainy nights. Clear skies give you the best view.

• Start your trek early. You’ll need to be at the crater before 4:00 AM.

• Skip full moon nights. The bright moonlight makes the flames harder to see.

What to Expect During the Ijen Volcano Night Hike

The Ijen Volcano night hike starts at the base near Paltuding. Here’s what you can expect:

• Length: Around 3 km (1.8 miles) to the top.

• Time: 1.5–2 hours uphill, 30–45 minutes into the crater.

• Difficulty: Moderate to hard.

• Elevation: About 2,386 meters (7,828 feet).

• Gear Needed: Good shoes, a flashlight, a warm jacket, and a gas mask.

The trail is steep but safe. Your reward is a view few people in the world ever see.

Ijen Crater Lake: A Stunning Sunrise Bonus

After the blue fire fades, don’t rush back. Stick around for the sunrise over Ijen Crater Lake.

This lake is one of the most acidic in the world. Its colour is bright turquoise. When the light hits it, the view is magical.

The sulfuric lake in Ijen Crater is highly toxic. So stay on marked paths and don’t get too close.

The Story of Sulfur Mining in Ijen Crater

The sulfur miners of Kawah Ijen are part of the story. These men carry heavy chunks of sulfur up steep paths. Each load can weigh up to 90 kg.

The mining is hard and dangerous. But tourism has helped. Some miners now work as guides or porters for trekkers.

Seeing them work adds another layer of meaning to your trip.

How to Join an Ijen Blue Fire Tour

You can book an Ijen Blue Fire Tour from several places:

• Bali (Ubud, Lovina, or Pemuteran): Longest trip, includes a ferry ride.

• Surabaya or Malang: Often part of a Bromo–Ijen combo tour.

• Banyuwangi: Closest starting point. Just 1–1.5 hours to the base.

Most tours include:

• Pick-up and transport

• Entrance ticket

• Water and sometimes snacks

Make sure to choose a responsible tour provider like Ijen Expedition Tour, known for ethical and eco-conscious services.
