Who would doubt the splendor of tGunung Raung, Gunung Raung Nature Reserve, Cagar Alamhe mountain roar? Mountain in East Java include “12 large” peak Indonesia. This unique title to twelve mountain peaks with an altitude above 3000 m above sea level. Glory Raung not only measured by the level of difficulty of the track, but also excess challenge. Not all climbers can reach the true summit of this mountain. Through normal routes, the village Wringin source, the climbers stuck up to his lips just a crater, about 3100 mdpl.

From the normal route, if you want to reach the top we have to melipir true crater lip. This is obviously a dangerous job, even if I may say nearly impossible. One little, the lives at stake. That is why, until now no one has succeeded.
Raung true summit is 3328 m above sea level and located on the south side. From the description of the villagers, known to have several times made efforts culminated several teams, both local and foreign tourists. However, nothing worked. That’s what brought the team from Mapala UI in April 2003 before climbing the south side, precisely at Glenmore District, to conduct a true assessment of the top Raung.
The first challenge is presented roar of the forest vegetation is very dense and thorny. After the obstacle is overcome, the next hurdle characteristic gap between the top route to true.
Local residents named the gulf as “poor rainfall,” which means the gap in the cross. From the various stories, this is where all the previous expedition failed.
But the existence of “poor rainfall” is not we met during the climb to reach the highest peak. Perhaps, what is meant by poor rainfall are the two major rivers that cut through the valley alongside the south side of the mountain roar into two parts of the region and the region Kalibaru Glenmore.
The myth that has been missing now for our team and a population that we made reporter managed to summit without the need to go through and get stuck in a very poor bulk legendary for locals.

Rich Creatures
In route we explore the Glenmore point, it took five days to reach the border areas of vegetation that had not found the plants. Beneath the forest was very dense with a variety of different animals, are still found occasionally passing hornbill birds above us, gibbons, and the snakes are large.
This region is also suspected as the region Javanese tigers had been declared extinct. But some residents still believe that the Javanese tigers are still there. If viewed from the thick forest, it was possible endangered species like tigers Javanese life.
Besides the presence of animals above, there is a major treat of the glory Raung kawahnya. Raung crater is the largest crater in Java with a diameter of nearly 2 km and a vertical depth of 500 m, where in the middle of the crater rising 100 meter high mountain formation that is always pulled out the white smoke of sulfur.
Raung including little-known people even interested climbers. This is because the climb is still little information is up to the roar and the mountain forests that covered the meeting route, which practically virgin field is what brought us to admire the largest crater in Java.
Raung tourism objects not so interested visitors as famous as the lack of tourist attraction located on the east, Ijen crater area. In Ijen we can see beautiful scenery, so that local and foreign tourists every day watch charm interspersed Ijen Crater workers carrying sulfur.

Two New Routes
Towards the top there is now a true roar of two new routes. The first, Kalibaru line. The line was considered difficult because after passing the limit of vegetation, climbers are faced with a steep ridge thin and sandy with a slope between 40-70 degrees.
For Kalibaru path that has been initiated by the Nature Lovers Club Pataga UNTAG Surabaya in 2002 the most difficult and challenging the adventurous, because they have passed the peak of Mount Wates. Down the mountain climbers must Wates and came back a little flat, towering mountains that create a deep chasm. If you want to climb a peak through the thin walls or the Travers at 50 m cliff along one wall of this pugunungan.
After that semi-scrambling climbing with safety ropes course along the wall of the highest puncakan easily fall out with Travers to the east side for the past two in a new abyss and then straight to climb to the top.
The second new track is Glenmore. This new route pioneered Mapala UI in May. This route is not directly obtain the highest peak, but must first pass Glenmore peak height of 3277 m at the highest peak east side. After that a new crater lip along melipir Raung west which is the highest peak. After passing the limit of vegetation, the top of the ridge line Glenmore thin enough and the left and right of the sliding sand if trodden on. Here, it took two hours to reach the top of the boundary vegetation Glenmore.
If lucky, sunny weather after the rain-we’ll see spectacular views on the west side two-storey-high waterfall pouring into the 100 meter large overdraft Kajarolo river jurangnya. Was in the back, there is the view south coast of Banyuwangi comb to the Bali Strait. As night began to spread, lights sparkled the two cities and Kalibaru Glenmore.
Along the crater lip in the effort needed extra care because of our right of vertical 500-meter crater and left a valley with a slope of 40-70 m and sandy rock slide. Although no more than 1 km when measured horizontally, from peak to peak Glenmore true it takes about a full day because of the way to half-crawl. Rather than point Kalibaru, Glenmore more friendly. Therefore, we will easily find quite a lot of water. Water is contained in the inlet-inlet on the cliff.
To get to the highest peak is better to spend the night if it was approaching evening, tomorrow morning we can catch the sunrise from the east. You are advised not to stay long at the top. Usually by 8 o’clock the fog continued to cover the top of this, and you do not get the best view.
Climbing tools are absolutely necessary. Javanese mountain climbers often called mountain timuran roar as the hardest mountain to climb in Java. General Sumberwringin on track, people must do scrambling and had to be careful no-load. Character south side seputaran Raung highest peak at almost the same basic form of rock and sand that easily fall out. So prepare extra equipment such as rope-karmantel at least 50 m, harnes, figure, long pegs, and a small shovel or ice ax, if you intend to climb the toughest mountains in East Java for any route you choose.

At over 2 kilometres in diameter, Gunung Raung has the largest crater in Java. It’s one of the most remote and least climbed of the 3000-metre plus peaks which means that there isn’t much litter on the trail and it really is a mountain to escape from civilization for a while. Lots of people do see the immense and impressive crater from the air as it is on the flight route from Java to Bali. Raung last erupted in 2008 but there hasn’t been a catastrophic eruption for many decades. It is worth looking at the excellent old photos of thew 1913 eruption which are available online.

Whilst reaching the true highest point of Raung crater rim requires a lengthy expedition involving roped rock climbing, the most popular route to the rim itself is from the north at Sumberwringin, where accommodation, guides and porters can be arranged. From the actual starting point, strong hikers could reach the rim in just over 7 hours, requiring about 5 hours to descend.

From Sumberwrigin (729m), it’s a 40 minute ojek or truck ride to the starting point in pine forest (1,206m). There are a couple of forks in the path near the start so a guide is a very good idea indeed. It is a long trail, but not especially demanding as the gradient is, for the most part, rather gentle. Raung itself is still quite some distance off, so the trail is actually very pleasant and gentle and it slowly leads you higher up the mountainside up through wild vegetation and scattered pine woodland. Look out for long-tailed black monkeys in this area. There is a nice spot to sit and rest for a while next to a cement trig (1,806m).

In the distance to the right (west) you should be able to see the large mountain of Argopuro rising above the clouds. To the left (east) is a smaller mountain called Gunung Suket, a nice shapely peak just a few kilometres from Raung itself. There are several spots to camp on the trail, but none of them are large enough for more than about 5 tents. They are also on slightly sloping ground. The best two are at 2,337m (no views but warmer) and 2,807m (colder but excellent sunset views over Argopuro). The latter is just 15 minutes from the treeline and would be ideal for anyone wishing to climb to the rim for sunrise.

At the treeline there is a small memorial (2,954m) presumably to someone who perished on the mountain. From here to the rim is about an hour of clambering up steep, bare volcanic rock. It’s pretty easy to climb up this way, but coming down you will probably need to use you hands in a few places to prevent slips and falls. To your left, between Suket and the side of Raung you might be able to spot the massif of Ijen-Merapi pushing through the clouds and the smaller mountain of Baluran inbetween.

Finally you will reach the edge of the crater rim (3,180m) and be rewarded with absolutely stunning views over the vertical crater walls. Take care here as a fall would mean certain death! The caldera is massive, and in the centre is a deep crater, approximately 400 metres across, which sometimes spews gas and rocks. The true highest point of Raung can be seen on the other side of the rim, over to the right (west). It is pretty much impossible to reach the peak from this side but you should be content with what is one of Java’s most amazing panoramas.

The true highest point of the crater rim, Puncak Sejati, is very difficult to reach and requires an expedition team who are confident with rock climbing and using ropes. Perhaps once a year a team from one of Indonesia’s universities attempts to reach the true peak. Below is some information from a Java Lava forum regarding how best to tackle the tricky top itself:

The first route, employed by OEC Surabaya, is thru Kalibaru Village. This route is considered more difficult than Glenmore route (see below). After the vegetation border, climber should reached Wates Peak first, go down, traversing 50 meter / 164 foot cliff wall, and then semi-scrambling on loose-rock slope to reach the summit. Most of the routes after the vegetation border is about 40-70 degree slopes on the loose-rock ground. Water is also difficult to find on this route, so it must be prepared and carried along from the base. The whole route from Kalibaru to the summit is said to be 17.6 Km /10.9 miles long.

Glenmore Village is starting point for the second route and was done by reaching the Glenmore Peak (3227 meters /10587 feet) first which is situated on the east of the main summit. When OEC-UI made their route, they did it by traversing the crater rim from the Glenmore Peak to the main summit which is located in the west of it. Horizontal length between the two peaks is less than 1 Km/ 0.621 mile, but it was said to take whole day to accomplish and most of it was done by crawling. The terrifying factors here is the vertical drop down to the crater 500 meters / 1,640 feet below on the right side and the 40-70 degrees slippery sand-loose-rock slope on the left side. But according to the hikers, this route is easier compared to Kalibaru route, as it is easier to find water along the way.

It is also encouraged to bring along climbing gear as the characterisitic of the southern side is exactly the same as the northern side i.e. sand and loose rock. Rope 50 meters / 164 feet, harness, figure eight, long pegs, (ice) axe were among the essential gear to have.”

Getting there

The nearest major airport is Surabaya and it’s a long, long drive. It can take anywhere between 5 and 9 hours. There is a small airport at Ketapang (Banyuwangi) but there are only very limited flights. From Bondowoso, head towards Wonosari before turning up towards Sumberwringin itself.


Basic accommodation available at Sumberwringin. A wider range of places can be found at nearby Ijen.


No major issues here – you may need to pay a small fee at Sumberwringin.

Water sources

There is no water available on the usual crater rim route from Sumberwringin so it’s vital that you take enough with you.
