Climbing Mount Raung Indonesia - Natural Form and History

Natural Mount Raung Indonesia - Natural history

Mount Raung is a part of the Ijen mountains, the easternmost mountains on Java island. These mountains extend across 4 regencies of East Java: Bondowoso, Jember, Situbondo, and Banyuwangi. What sets Raung apart from the rest is its 2km wide and 500m deep caldera, which was actively smoking as of mid-2019.

Natural Mount Raung Indonesia - Climbing history

Mount Raung is one of Indonesia’s 130 active volcanoes. The earliest recorded eruption took place in 1586 and there were many fatalities. There were a few more eruptions between 1586 and 1817, out of which around five were deadly. The last eruption took place in July 2015. The airport had to shut down and all flights to the area were cancelled. Many were asked to evacuate from the surrounding areas.

Natural Mount Raung Indonesia - Current status

Mount Raung is not a popular hike. It is (probably) the hardest summit to bag in all of Java, so it is generally not feasible for the majority of amateur climbers. Its volcanology turns off others. This all means that those that have the skills and the daring to climb it, they’ll enjoy a climb that is more private and challenging.

Climbing Mount Raung Indonesia - Trail options

Number of options

There are 2 popular trails to climb Mount Raung. The first is via Sumber Wringin, Bondowoso and the second is via Kalibaru Jember.

Time to complete
3 days

The Kalibaru Trail actually takes climbers to the highest peak of Mount Raung, requiring technical climbing skills with ropes.

Number of days
Day 1

Leave your hotel in Kalibaru and head towards Post 1 via hired vehicle or more popularly, an ojek bike.


Start the trek from Post 1 to Post 7. This is an uphill hike but it’s quite doable from Post 1 to Post 4. The trek from Post 4-7 is rather narrow and slipping to the left or right is a dangerous, steep drop down.


Once you’ve arrived at Post 7 you’ll be spending the night here.

Day 2

After breakfast you can repack your stuff to get back on the trail. Today you will be going from Post 7 to Post 9. You’ll be hiking from early morning ‘til around early afternoon and this is still a very steep climb up a narrow path. In fact, it can be likened to taking 3-4 steps of a staircase at once. However, the terrain will be more rocky and not as dense with tropical jungles like before.


Once you’ve reached Post 9 it’s time to set off to the four summits, starting with a 3-4hour hike to Puncak Bandera.


From Puncak Bandera you can take the Sirothol Mustaqim to reach the 17th Peak Summit. The next summit is Tusuk Gigi and finally you’ll reach the true summit, Puncak Sejati.


From the true summit take a 5 hour descent to Post 7 for an overnight camp.

Day 3

There may not be a rush but get an early start to the day as you have a 5-6 hour trek downwards from Post 7 to Post 1.

Climbing Mount Raung Indonesia - Safety & Accessibility


It seldom rains in the area, however there is the occasional drizzle. There’s a bit of wind and it feels cold while hiking but at the summit it’s surprisingly warm.

The best time to visit is between April to October. It’s best to avoid traveling during Ramadan as guides may not be available.

Climbing safety

The climb is quite safe, but is a rather technical. The terrain involves tropical dense jungles from Post 1 to Post 7. From Post 4 to Post 7 the path starts narrowing. The climb becomes most dangerous towards the end. At the exposed area after Puncak Bandera, the ridge before the caldera rim, the area is rather slippery. You’ll be doing a lot of scrambling and there are many loose rocks. It’s always best to check for a steady grip, before you transfer all your weight when climbing. The drop is rather steep if you slip anywhere from Post 4 to the Summit. There will also be a bit of abseiling involved. Here your guide will be fixing the ropes to help as there are no fixed ropes along this trail.

Personal safety

It’s always best to keep your belongings with you at all times. There are no imminent dangers along the way, however note that this climb is a rather secluded climb and you won’t be bumping into many faces along the way.

Permits, Fees, and Regulations

Permits are compulsory and can be arranged through your guide. In fact, the guide should have all the technical equipment necessary for the climb as well. You can find a lot of guides on Instagram or other social media platforms and it’s always best to make arrangements for one as early as possible. Along the way, your guide will be bringing the water for cooking, but you’ll need to take your own supply of drinking water.

Emergency contacts

Police: 110 (112 from mobile)
Ambulance: 118 or 119

Getting there and away

The Surabaya Juanda International Airport is nearest. You can take a cab to the train station and from there it’s a 5 hour train ride to Kalibaru.

Money Matters

The entire cost of this climb should cost you around $40 USD if you’re a local. The cost for foreigners usually varies between $150-250 USD.

Climbing Mount Raung Indonesia - Special Tips

Tips for amateur climbers

This is probably not a climb to attempt if you’re still an amateur and inexperienced with rough terrains. There’s a lot of scrambling involved, as well as some abseiling.

Tips for advanced climbers

If you’re a seasoned climber, the abseiling challenge is quite exciting. Even the steep climb in itself is quite the motivating challenge for an advanced mountaineer.

Tips for women

Women climbing Mount Raung should not face any special challenges. However, it is best to travel in groups and use a professional and reputable guide or tour service. Avoid unwanted attention or cultural faux pas by taking your dressing cues from locals (who tend to cover shoulders and legs, even when swimming).

Tips for responsible / safety-conscious climbers

Given the lack of facilities, and that you’ll need to bring water with you, please bring your empty water bottles with you to dispose of appropriately. 

Tips for trail runners

No trail running events take place on the mountain at present. There isn’t likely to be one to the summit, as its technical difficulty is prohibitive to runners.

Tips for nature lovers

East Java does have some nature, but with Mount Raung not sitting in any national park, the area is a bit less pristine than others in Java.
