Mount Ijen Tour: Explore Java’s Blue Fire Phenomenon

Tucked away in the eastern highlands of Java, Mount Ijen is one of Indonesia’s most extraordinary natural wonders. Famous for its surreal volcanic landscape, this active stratovolcano offers a rare spectacle found in only a few places on Earth — the Ijen Blue Fire. Alongside this mesmerizing midnight glow lies a stunning turquoise acid crater lake, the largest of its kind in the world.

For adventurous travellers, an overnight Mount Ijen tour offers the chance to experience both of these rare natural wonders in one unforgettable journey. Whether you’re coming from Bali, Surabaya, or Banyuwangi, this trip promises jaw-dropping views, unique encounters, and memories that will last a lifetime.

What Makes Mount Ijen So Special?

The main highlight of Kawah Ijen — the name of the crater — is the rare blue fire phenomenon. Unlike lava, which glows red or orange, the blue fire results from ignited sulfuric gases that emerge from cracks in the volcano. These flames can rise to five meters high and are only visible in complete darkness, making a night hike essential.

The crater lake, with its otherworldly turquoise colour, is just as remarkable. Containing more than 27 million cubic meters of extremely acidic water, it is the largest highly acidic lake on Earth. The lake’s pH level is close to zero, and the surrounding environment often emits a sharp sulfuric odour, especially near active vents.

Due to the need for complete darkness, the IjeBlue Fire tour begins around midnight, allowing trekkers to witness the phenomenon before the sun rises. As daylight breaks, the landscape transforms, revealing a dramatic contrast of smoky vents, the glowing lake, and sulfur miners at work.

Mount Ijen Tour Options: From Bali, Surabaya, or Banyuwangi

There are multiple ways to join a Mount Ijen tour, depending on where you begin your journey:

• Tour from Bali to Ijen:
  Many travellers choose this option. The journey typically begins with an afternoon drive from Ubud, Canggu, or Seminyak to Gilimanuk port in West Bali. After a short ferry ride to Java, you’ll continue by car to a local hotel in Banyuwangi, the nearest city to Mount Ijen. The hike begins around midnight after a short rest.

• From Surabaya:
  If you’re travelling from East Java’s capital, expect a 6–7 hour drive to Bondowoso or Banyuwangi. Many tours offer hotel pickup in Surabaya and include an overnight stay near the base of Ijen volcano Java.

• From Banyuwangi:
  This is the closest and most convenient starting point. It takes just 1.5–2 hours by car to reach the IjenCraterr hike trailhead. Ideal for travellers with tight schedules or those already exploring East Java.

Popular tour packages often include transport, entrance fees, a local guide, gas masks, and sometimes meals. Whether you’re on a private or group tour, it’s best to book in advance, especially during the dry season.

What to Expect During the Tour

Your Ijen crater hike typically begins around 1:00 AM. The climb to the crater rim takes about 1.5–2 hours, covering 3kilometress on a moderately steep trail. It’s dark, quiet, and often chilly, so dressing appropriately is key.

Once at the top, you’ll descend another 30–40 minutes into the crater to get close to the blue fire. This part of the hike is challenging due to loose rocks and strong sulfur fumes. A gas mask is essential here, and most tours provide them.

During the descent, you’ll encounter sulfur miners carrying heavy yellow rocks out of the crater. These workers are part of Mount Ijen’s unique character and deserve both respect and space.

As dawn approaches, the fiery blue glow fades, and the crater reveals its stunning acid lake and smoky vents. Watching the sunrise over the volcanic ridge is an unforgettable moment. By 6:00–7:00 AM, most hikers begin their descent back to the parking area and return to their hotels.

The Mount Ijen tour can be physically demanding and requires careful preparation. Here are a few essentials to pack:

• Warm clothing: temperatures can drop below 10°C (50°F)

• Hiking shoes with good grip

• Drinking water and light snacks

Best Time to Visit Mount Ijen

The best time for an Ijen blue fire tour is during the dry season, which typically runs from April to October. During these months, the skies are clearer, and the trails are safer for hiking.

The blue fire is visible year-round, but avoid visiting during the rainy season (November–March), when heavy rain and fog can obscure visibility and make the hike more dangerous.

For the most vibrant views and safest conditions, aim for a tour between May and August.

Responsible Tourism and Local Insight

Mount Ijen is not just a tourist attraction — it’s also a workplace for local sulfur miners who endure extreme conditions for modest wages. As visitors, it’s essential to respect their space, avoid blocking their paths, and never touch or take the sulfur they carry.

When booking your Mount Ijen tour, consider choosing ethical tour operators who support the local community and provide fair wages for guides and staff.

Help preserve this incredible site by avoiding littering, staying on marked trails, and using eco-friendly travel practices. A little mindfulness goes a long way toward preserving Kawah Ijen for future generations.
