Mount Sindoro is separated from its similarly conical but slightly higher neighbour, Gunung Sumbing, by the Kledung Pass (1,404m). Together, they dominate the Dieng plateau area and can both be climbed from Kledung village where there is a decent hotel. There is another straightforward and slightly shorter ascent from the north at Sigedang (1,900m). From Kledung it takes 5 – 6 hours to the top and from Sigedang a little less – maybe 4 hours for fast hikers. For its size, Sindoro is an easy hike and would make a great introduction to hiking in Indonesia. From the top there are great views to Sumbing, Merapi, Merbabu, Ungaran, Slamet, Dieng plateau’s high ridge Gunung Prau and the north coast of Java. Sunrise is usually magnificent so it is worth climbing overnight. Camping is not advised at present (2014) due to poisonous gases at the top (since 2011 – one hiker died camping by the crater in 2013). Though there is a small lake at the top, there is no water source on the actual route so make sure you take plenty with you.
From the main road at Kledung, take the cobbled road leading north opposite the Kledung Rest Area. It is difficult to miss because it’s the first turning east of the Kledung Pass hotel. The cobbled road leads gently up the hillside for about one mile and it is recommended you get an ojek (motorcycle taxi) to take you up as far as possible. The end of the road is at 1,654m. The well-defined and occasionally slippery trail leads up through pine woodland past the remains of Pos 1 (1,761m), Pos Payungan (1,857m), across some very small wooden bridges and on to the remains of the shelter at Pos 2 (1,978m). There are a few good places to admire the views of Sumbing across on the other side of the Kledung Pass but it is not until the first major camping area (pos 3 at 2,320m) that the vegetation becomes sparse. If you are going to camp anywhere other than at the summit (not advised at present), Pos 3 is recommended because the views south and east are spectacular and there is plenty of room for tents. However, there are many places suitable for just one or two tents all the way up.
The trail climbs more steeply and passes scattered rocks, notably ‘batu tatah’ (at 2,843m). There is little shade here so for the light-skinned it is essential to use sun cream during the day. Finally the top is reached and you are on the edge of Sindoro’s crater. There are actually two craters next to each other: a deeper, water-filled one (2010, no longer any water by 2014, but lots of fumarole activity) and a smaller swampy one higher up. If you follow the crater rim round to the right (east), it descends to a large, flat grassy area which sometimes has a small lake in it. This would appear to be the remains of a very old third crater. It would make a great place to camp. Further round, is the alun-alun, an even larger area, perfect for camping. However, given the present fumarole activity it is not recommended at present (2014) to camp near the top. Check with guides or local people regarding the situation in future.
Much of the crater rim is of a very similar height. It takes only 30 minutes to circuit the crater rim so baggers don’t need to worry too much about missing the very highest point if they’ve had a wander around the crater edge! The highest reading I got on my GPS was on the edge of the crater just above the small depression where there is often a small pool of water. In clear weather you can see the north coast of Java. The edelweiss-covered summit area is very large and flat and the mountain apparently takes its name from the fragrant scent of the edelweiss flowers.
Fast hikers can be back down at the Kledung Pass hotel in less than 4 hours. You may even be able to arrange an ojek from a local farmer when you reach the cobbled road.
Route from Sigedang / Sikatok: The first two posts (Pos 1/2) are an hour and two hours respectively from Sigedang tea plantation and are actually both tea-weighing shelters. From there it is less than 3 hours to the top. Full report on this report coming in October 2019…..

Gunung Kembang / Kembangan (2,340m)
To the south-west of Gunung Sindoro is a peak called Gunung Kembang (Kembangan on the Bakosurtanal map) which in 2019 is becoming a popular hike in its own right, having been officially opened as a new route in April 2018. It can be clearly seen just to the right of Gunung Sindoro from peaks in the Dieng area and it is no surprise that it is known as ‘Anak Sindoro’ (Child of Sindoro). There are two main routes as follows.
It is most commonly hiked from the south at Tambi tea plantation (1,350m) in Blembem near Wonosobo. The Pos enroute include Pos 1 Istana Katak and Pos 2 Kandang Celeng (at the end of the tea plantation), Pos 3 Liliput, Pos 4 Simpang 3, Pos 5 Akar and Pos 6 Tanjakan Mesra which is just 15 minutes before the top. The summit is open and has great views of Sindoro, Sumbing, Dieng and Slamet especially at sunrise. There is an old crater at the top called Bimo Pengkok. Strong hikers can be at the top in 4 hours and back down in another 3 hours.
The other route leads up from the west at Lengkong (1,500m) and it takes 2-3 hours to reach the top. Registration closes at 11pm.
- Getting there: Buses between Purwokerto and Semarang run through Kledung. From Yogyakarta, take a bus to Magelang and a second bus to Wonosobo. Kledung is just under 3 hours from both Yogyakarta or Semarang by car. The Sigedang trailhead is around 2.5 hours from both Pekalongan and Semarang where there are train stations. Weleri, which lies in between the two cities, is only 1.5 hours from the trailhead but currently (2019) no executive class trains stop here.
- Accommodation: The Kledung Pass Hotel is the obvious place to stay.
- Guides and GPS Tracks: Looking for a guide? Need GPS tracks and waypoints? Join Gunung Bagging Premium here.
- Permits: Your guide will arrange it for you – take a photocopy of your passport photo page if climbing without local help. Be sure to check with local people about the volcanic activity near the crater as it may not be safe to climb.
- Water sources: Unreliable on the ascent from Kledung- take sufficient supplies with you. Usually a limited amount at the top.
- Travel insurance: We recommend World Nomads insurance, which is designed for adventurous travellers with cover for overseas medical, evacuation, baggage and a range of adventure sports and activities including mountain hiking.

Origins and Meaning
Lordly Mountain. Sindoro probably comes from the Javanese si (a kind of “title” or “person marker”) and ndara (pronounced /ndoro/) or bandara (pronounced /b’n.doro/) meaning “lord, master”. (George Quinn, 2011)
