The Stunning Kawah Ijen in a Nutshell
Mount Ijen is an active volcano in East Java, straddling the border between Bondowoso and Banyuwangi. It draws travelers from all over the world with its rare blue fire phenomenon—one of only a few places on Earth where this natural wonder can be seen, and the only accessible one in Indonesia.
This mesmerizing blue fire glows from the crater of Mount Ijen, also known as Kawah Ijen. The volcano’s eruption long ago formed a large caldera, creating a lake filled with turquoise water rich in sulfur. Although the water is warm, it is highly acidic, so touching or drinking it is strictly prohibited.
Kawah Ijen is more than just a tourist attraction; it also serves as a vital source of livelihood for local sulfur miners. Visitors can observe the miners at work and even engage with the local community, offering a glimpse into their daily lives.
Also, the summit of Mount Ijen provides breathtaking views at sunrise, with surrounding mountains like Mount Merapi and Mount Papak framing the horizon.
Since the volcano remains active and continues to emit sulfur gasses, it’s important to monitor current conditions before visiting. Make sure to bring a health certificate, a required document since the beginning of 2024.
But worry not, we’ve covered all these essential points in the following sections. Keep reading for detailed tips on preparation, transportation, safety guidelines, and the best ways to enjoy your adventure at Kawah Ijen!
Where is Kawah Ijen
Kawah Ijen sits on the border between the Banyuwangi and Bondowoso regencies in East Java. The only official hiking route is through the Paltuding Post, located 1,800 meters above sea level at the intersection of the Bondowoso and Banyuwangi routes. You can reach the post by private vehicle or public transportation, which will take you to the Ijen hiking gate. From there, all vehicles stop, and you’ll embark on a 3.4-kilometer hike along a relatively easy trail.
Starting Your Adventure at Kawah Ijen
Your journey to Kawah Ijen begins at Paltuding Post, located at the base of Mount Ijen. This is the official entrance gate where you’ll find the ticket counter. If you travel without a tour, entry tickets must be purchased online, but paid at the counter. The daily visitor quota is limited to 2,000 people, so if you’re visiting at the peak season, it’s better to book well in advance.
From Paltuding, the hike to the summit covers 3.4 kilometers along a trail that varies in terrain but is generally easy to follow. The hike usually takes 2.5 to 3 hours.
At the Paltuding Post, you’ll find plenty of small warung stalls selling essentials like drinking water, snacks, and coffee. You can also rent a gas mask for around IDR 45,000 (USD 2.80), which is highly recommended due to sulfur emissions at the crater.
Once you reach the summit, you’ll be rewarded with some of Ijen’s most spectacular sights—the famous blue fire, a stunning sunrise, and a breathtaking view of the turquoise crater lake. You’ll also get the chance to observe the sulfur miners at work, using traditional methods to extract the valuable mineral.
Basic Information
- Operating Hours: The Paltuding ticket booth is open from 2 AM to 12 PM.
- Ticket Price: For international visitors, tickets cost IDR 100,000 on weekdays and IDR 150,000 on weekends (USD 6.46–9.69), excluding insurance (which is extra 5,000 IDR).
- Online Tickets: Entrance tickets must be purchased online via tiket.bbksdajatim.org.
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.

Ijen Crater Regulations
Before visiting Kawah Ijen, there are a few important rules you need to follow to ensure your safety and preserve the environment.
Using a Guide is Mandatory
All visitors are required to hire a guide when trekking to Ijen Crater. If you’re traveling on your own and not part of a tour, you can hire a local guide at the entrance post—just remember to negotiate the price.
Health Certificate is Required
Visitors must present a health certificate to enter Ijen Crater. This is to ensure that all hikers are fit for the trek, which involves steep climbs and exposure to thin air and sulfur fumes. You can get a health certificate at a Hospital, Puskesmas or Clinic in Banyuwangi (the closest city) for around IDR 40,000 – IDR 100,000 (around USD 2,5 – USD 6,64) per person. People with asthma, heart conditions, those weighing more than 100 kg, pregnant individuals, and children under 3 years old are not permitted to enter.
It might also be worth asking at your accommodation, as some of them are authorized to issue the certificates.
Wear Safety Equipment
Make sure to use complete and proper hiking gear, such as trekking shoes, a jacket, a mandatory gas mask, and bring a flashlight.
Book Ticket Online
If you’re not part of any tour, you’ll need to book your ticket online at tiket.bbksdajatim.org. Upon arrival, present your booking barcode at the ticket counter on the specified date and make the payment. Keep in mind that tickets must be booked online in advance—without one, you will be denied entry.
No Motorbikes Allowed
Motorized vehicles, especially automatic motorbikes, are not permitted on the trail to protect the environment and maintain safety. The Paltuding Post serves as the final point where vehicles are allowed.
Do Not Litter or Damage Property
Help preserve the beauty of Ijen by avoiding littering or vandalizing signs and markers. Damaging property is a violation and may result in fines or penalties.
No Camping at the Summit
Camping at the summit is strictly prohibited, as the toxic sulfur gasses emitted by the active volcano make it unsafe for overnight stays.
Avoid Cliff Edges
Stay away from cliff edges, as the rocks can be fragile and unstable, posing a serious fall risk from a height of 175 meters. Follow the marked boundaries for your safety.
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.
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.
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
- Surabaya to Banyuwangi: ~6 hours
Since the journey can be quite long, it’s recommended to stay overnight in Banyuwangi before continuing your hike to Mount Ijen.

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.
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.
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.
