Hidden in the mountains of East Java, Kawah Ijen is home to one of the rarest natural wonders on Earth: the electric-blue fire that burns from deep within its volcanic crater. Visible only in the darkness before dawn, this glowing phenomenon draws adventurers from around the world—and it’s only one part of what makes the hike up Mount Ijen so unforgettable.
In this complete travel guide, you’ll find everything you need to plan your own trip to Kawah Ijen—whether you’re going solo or with a group. I’ll cover practical tips, what to expect on the trail, how to get tickets, and the easiest routes from Bali and Java. Let’s dive in and get you ready for an epic adventure.
Introducing Kawah Ijen: Home of the Rare Blue Fire
Kawah Ijen, located in Mount Ijen, East Java on the border of Banyuwangi and Bondowoso, is one of the only places on Earth where you can witness the rare blue fire—a natural phenomenon caused by ignited sulfuric gases glowing in the dark. It’s the only spot in Indonesia where this can be seen up close at an altitude of 2797 above the sea level.
The crater also holds a striking turquoise lake, rich in sulfur and highly acidic—beautiful, but not safe to touch. Kawah Ijen is not just visually stunning; it’s also home to local sulfur miners, whose tough daily work offers a glimpse into the region’s culture and resilience.
That’s why Kawah Ijen is so popular among both local and international tourists. It has become one of the must-visit destinations when exploring the island of Java. At sunrise, the summit rewards hikers with panoramic views of nearby peaks like Mount Merapi and Mount Papak.
Since the volcano is active and emits sulfur gases, visitors are required to bring a health certificate, a rule introduced in 2024.
Starting Your Adventure at Kawah Ijen
Your journey begins at Paltuding Post—the main entrance to the exotic Kawah Ijen. From here, you’ll start a hike of around 3 kilometers, which usually takes about 1.5 to 2 hours.
The trail starts off gently, with a wide and relatively flat path. At this point, you might feel like it’s an easy walk. But halfway through, the trail becomes steeper, narrower, and more challenging.
Things get even more intense as you descend into the crater to witness the blue fire up close. The path is rocky and steep, so be sure to watch your step. Still, the hike is doable even for beginners.
Just make sure you’re well-prepared with a few essential things before starting your Kawah Ijen adventure.
Buy Tickets Online
All entrance tickets to Kawah Ijen must be purchased online through the official website: tiket.bbksdajatim.org. Daily visitor numbers are limited to 2,000 people, so be sure to book your ticket well in advance—especially during peak season.
For international visitors, the ticket price is IDR 100,000 on weekdays and IDR 150,000 on weekends. Payment is made at the ticket counter by showing the barcode you received after booking online.
If you’re joining a tour, your guide will usually take care of the ticket booking process for you.
Note: Kawah Ijen is closed on the first Friday of each month for area maintenance and mountain clean-up. This is carried out by local authorities and the surrounding community.
Health Certificate Required Before Hiking
Before your trip, you’ll need a health certificate to be allowed to hike Mount Ijen. This certificate is used to ensure you’re physically fit—especially to confirm you don’t have any respiratory issues.
You can get the certificate up to 7 days before your hike (at the latest) at a hospital, community health center (Puskesmas), or clinic around Banyuwangi—the nearest city to the mountain.
The good news is, there’s now a medical post right at the Paltuding entrance gate. They provide health checks and issue certificates, including post-hike checkups. The post is open all the time, so you can easily get your certificate right before your hike.
Wearing a gas mask is Mandatory
Wearing a gas mask is mandatory, as the high sulfur levels at Kawah Ijen produce a strong smell—similar to boiled eggs—have low oxygen levels, and can irritate your eyes.
You can rent a gas mask at small stalls near the entrance gate at Paltuding Post for around IDR 45,000.
While you might get past the officers without one, you’ll likely regret it. Without a mask, the toxic fumes can sting your eyes and make it hard to breathe—making it almost impossible to enjoy the famous blue fire view comfortably.
Consider Hiring a Local Guide
While it’s possible to hike Mount Ijen without a guide, if it’s your first time visiting—and especially if you want to see the blue fire up close—it’s highly recommended to hire a local guide. They know the terrain and weather conditions well and can share valuable insights about the area.
More importantly, they’ll help ensure your safety throughout the journey, particularly during the tricky descent into the crater to view the blue fire.
Note: The hike may be canceled if weather conditions are poor or if it rains. The trail can become slippery, visibility may be low due to fog, and sulfur gas levels can rise, making it harder to breathe.
What To Do and See in Kawah Ijen
Kawah Ijen offers more than just a challenging hike—it’s a truly unique destination filled with rare natural wonders and cultural experiences. Whether you’re chasing dramatic views or looking to connect with local life, here are some of the highlights you won’t want to miss:
Blue Fire
The Blue Fire is a rare natural phenomenon which occurs when molten sulfur and sulfuric gasses, at extremely high temperatures, come into contact with oxygen, producing a glowing blue flame that resembles fire.
This phenomenon is only visible in the dark, making night or early morning the best time to witness it. It’s recommended to begin your hike around 1 AM or 2 AM to arrive at the crater in time to see the blue fire, with sunrise occurring between 5:30 AM and 6:00 AM.
You can view the blue fire from the rim of the crater, though the visibility might not be ideal. For a better view, you can descend into the crater, but be aware that the trail is steep and challenging. Stay cautious and follow your guide closely to avoid any risks.
It is mandatory to wear a gas mask due to the sulfur fumes, which can severely affect your breathing and irritate your eyes. It’s also advisable not to linger for too long near the blue fire—if you begin to feel unwell, head back to the rim immediately.
The Beauty of Sunrise
The blue fire is visible early in the morning, from around 4 AM to 5 AM. After that, you can enjoy a stunning sunrise over the crater. As the sun rises, a sea of white clouds blankets the landscape, with the peaks of nearby mountains emerging in the distance. Sunrise typically occurs around 5:30 AM.
Ijen Lake
Ijen Crater Lake is a vast, turquoise-colored lake spanning 5,466 hectares with a depth of 200 meters. The water is warm but highly acidic, containing dangerous levels of sulfuric acid.
The lake was formed following Mount Ijen’s volcanic eruption, which left behind a large caldera. Touching the water is strictly prohibited—the combination of acidity and temperatures up to 40°C (104°F) can cause burns, irritation, or severe itching.
From the summit or along the lake’s edge, you’ll be rewarded with panoramic views of the surrounding mountains and volcanic peaks that encircle Mount Ijen. A popular photo spot near the summit features the trunk of a dead tree, offering a picturesque backdrop of the turquoise lake.
However, when taking photos, be cautious. Always watch your step and avoid standing too close to the cliff edges to ensure your safety.
Sulfur Miners
Watching the sulfur miners at Kawah Ijen is a unique and humbling experience. These men use traditional methods to extract sulfur, carrying loads of 70 to 90 kilograms on their shoulders from the crater to the summit and down to the basecamp. Many of them complete this exhausting climb 1-2 times a day, repeating the routine nearly every day.
Sadly, their work is extremely hazardous. The miners are exposed to hot, toxic sulfur fumes while earning only USD 17 to 20 per day. If you meet them along the trail, consider showing your support by donating or purchasing a small sulfur stone as a souvenir.
Mining at Kawah Ijen is widely recognized as one of the most challenging jobs in the world. To learn more about the severe impact on the miners’ health, you can read this article by the BBC.
Riding a Trolley Taxi (Pedicab)
One unique activity you can try at Kawah Ijen is riding a trolley taxi (pedicab) to the summit or on your way back down. While it might feel like cheating (and, to be honest, it kind of is), it’s a great option if you’re not feeling well, traveling with kids, or simply want to skip the hike.
Round-trip fares from Paltuding Post to the summit range between IDR 800,000 and IDR 1,200,000 (around USD 51.70 – USD 77.55) per trolley. While the fare may seem steep, it’s reasonable considering you’ll be escorted by a miner who will push the trolley all the way to the top. If you only need the trolley for the descent, the fare is more affordable, around IDR 200,000 (USD 12.92).
Each trolley can accommodate one adult or two children. These miners, experienced in carrying heavy loads, ensure a safe and comfortable ride. The trolleys are also equipped with brakes to control speed on steep downhill sections, so you can relax and enjoy the journey.

Safety Tips for Hiking Mount Ijen (Kawah Ijen)
Although Kawah Ijen is a popular tourist destination, proper preparation is essential for a safe and enjoyable hike. You don’t need to carry too much gear, since you won’t be staying long at the summit—but the essentials matter.
Here are some must-have items and tips to help you hike Kawah Ijen safely:
- Use hiking shoes with good grip
- Wearing Gas mask and a warm jacket (it can get very cold at night)
- Comfortable clothing that won’t snag on rocks or branches
- Headlamp, especially if hiking at night to see the blue fire
- Good physical preparation and enough rest before the hike
- At least 1 liter of drinking water to stay hydrated
- Snacks or chocolate to keep your energy up
- A small or medium-sized daypack for easy carrying
- Personal medication and a basic first aid kit
- Optional: Trekking pole to help with balance on uneven terrain
Important Safety Rules:
- Motorbikes are not allowed inside the hiking area
- Do not litter or damage the natural surroundings
- Camping is prohibited at the summit
- Stay away from the edge of the crater—it can be unstable and dangerous
By following these tips and respecting the rules, you’ll help keep the mountain safe for yourself, other travelers, and the local environment.
Backindo Tip: These regulations might seem strict, but they are essential. In 2024 alone, two tourists tragically lost their lives at Kawah Ijen. A Polish tourist died from exhaustion, while a Chinese tourist fell into the crater after her skirt got caught on a tree while posing for a photo.
Best Time to Visit Kawah Ijen
The best time to visit Kawah Ijen is between May and September, when the weather is clear, and there is rarely rain. During this period, you’ll have a better chance to see the blue fire clearly and safely. If you visit during the rainy season, the trail may become slippery and more dangerous. So, make sure to plan your trip during the right season.
Also, if possible try to avoid visiting on weekends or national holidays, as Kawah Ijen will likely be crowded with visitors.
Since the journey takes a significant amount of time, it’s recommended to carefully plan your schedule and, if possible, stay overnight near the basecamp or in Banyuwangi City.
How to Get to Kawah Ijen
There are several routes and options to get to Kawah Ijen. Here, I’ll provide some travel alternatives from both Bali and Java to help you reach this destination.
From Bali to Banyuwangi (Kawah Ijen)
The easiest and quickest way to reach Kawah Ijen from Bali is by bus. Book a bus ticket from Bali to Banyuwangi, which includes a ferry ride from Gilimanuk Port to Ketapang Port. The ferry crossing takes about 45 minutes. Make sure about the final stop of your bus as some companies will take you only to the port at Java (Katapang Port), while others will drive you to Banyuwangi.
If you’d like to know more details about how to get from Bali to Java, we’ve already covered it in our How to Get from Bali to Java
From Ketapang Port, Banyuwangi to Kawah Ijen
Most buses from Bali to Banyuwangi depart in the late afternoon, meaning you’ll arrive in Java late at night or early in the morning. I don’t recommend heading directly to Kawah Ijen upon arrival—it’s better to rest first. However, for your reference, the journey from Ketapang Port to Paltuding Post (the starting point for the hike) takes about 2.5 hours.
If you’re dropped off at Ketapang Port, you can take a car to your accommodation for a comfortable night’s rest. Be aware that Grab and Gojek pickups are restricted within the ferry terminal area, so you’ll need to walk over 500 meters to meet your driver. In this case, taking a regular taxi might be more convenient.

If you wish to continue your trip to Kawah Ijen from Banyuwangi by public transportation, head to Taman Sritanjung in Banyuwangi city center, where you can catch a DAMRI shuttle directly to Paltuding Post.
Keep in mind that seats on the DAMRI shuttle are limited (only 15 seats), so it’s best to book in advance through the DAMRI app, especially if you’re traveling on weekends. I really recommend the DAMRI shuttle. It is a convenient and affordable option, taking you straight to Paltuding Post, so you don’t need to worry about arranging additional transport.
Backindo Tip: As a foreigner, downloading the DAMRI app might be tricky. If you encounter issues, ask your accommodation staff to help with booking.
Getting to Kawah Ijen from Java
Train to Banyuwangi
If you are coming from anywhere in Java—Jakarta, Bandung, Yogyakarta, Semarang, or Surabaya—you can take a train to Banyuwangi Kota Station (BWI).
If you arrive at Banyuwangi Kota Station (BWI),you’ll be close to Taman Sritanjung, where you can take the DAMRI shuttle to Paltuding Post. To get to Taman Sritanjung, you can use Grab or Gojek.
Travel Time by Train
- Jakarta to Banyuwangi: ~19 hours
- Yogyakarta to Banyuwangi: ~10 hours

Flying to Banyuwangi
Alternatively, you can take a flight from to Banyuwangi Airport (BWX), which is much faster. From Jakarta it takes only 50 minutes. From the airport, you can hire a taxi to take you to Paltuding Post, with fares ranging from IDR 450,000 to IDR 550,000 (around USD 28.90 – USD 35.30). But as mentioned before, it’s highly recommended to check in to your accommodation and rest before starting the hike.
Backindo Tip: It’s best to rent a car from the station, port, or terminal, as the road to Paltuding Post is quite challenging, and public transportation (except the DAMRI shuttle) is rare.
Travel to Bromo and Kawah Ijen
Visiting both Mount Bromo and Kawah Ijen is a popular mountain travel experience. You can visit both mountains, but you need to allow enough time. If you are coming from Bali, it’s better to start with Kawah Ijen and then head to Bromo.
The journey from Kawah Ijen (Banyuwangi) to Cemoro Lawang Gate (Probolinggo) covers 236 km and takes about 7 hours by car or 5 hours by train.
Although public transportation is available, it’s more complicated—you’ll need to return to Banyuwangi City to catch a bus or train to Probolinggo, which can add extra time to your trip.
For a hassle-free experience, consider booking a tour guide service that offers combined packages for both Kawah Ijen and Bromo. If you’d rather not go with a random agency, I’d recommend checking the Klook or GetYourGuide portals to read reviews from fellow travelers. Below are some recommended tour services to help you plan your trip.
Where to Stay Near Kawah Ijen
If you plan to stay overnight before the hike, you can stay in the city of Banyuwangi or in Licin District (the closest location to the Ijen Crater meeting point). There are some homestays and accommodations close to the entrance, but water availability may be an issue at these places. For backpackers, camping is an option—you can pitch a tent at the campground near Paltuding Post.
The area around Kawah Ijen offers a wide range of accommodations, from budget-friendly options to luxury stays. To help you choose, here are our top recommendations for the best value for money:
