Until 2017, this peak was the most popular climb in Banten. It is less prominent and less high than nearby Gunung Karang but is more interesting. It is also a fairly easy hike – if you start early enough you can be back down in time for lunch and this is definitely a good idea as later in the day it would be unbearably hot. It is perfect as a last-minute day trip from Jakarta and takes just over two hours to get to in good traffic conditions.
However, there is one important issue to be aware of. Since 2017 or so, the original trail has been closed in Cilentung, and any hikers are encouraged not to use the trail. This is supposedly due to a landslide in the area making part of the trail impassable, but it seems likely there are other factors at play here, perhaps including the fact that there are possible dangers for local students camping at the crater and inhaling the gas. It certainly seems a strange decision to close the trail entirely, rather than simply modify rules and regulations, especially since some local people made money selling drinks and snacks on the trail in previous years and there is no legal reason why the trail should be closed.
Thankfully, the crater and summit can still be accessed from a different direction, but this only applies to small groups with special permission and who take a local guide with them. Citinggul, a village to the west of the peak and along the same road beyond Cilentung, is the place to start. As the trail is not official it takes a little longer and there are various spots in which you could become lost without local knowledge. There are a couple of un-marked places on the road where you could begin your trek to the mountain, both a little over 400 metres in elevation.
Notable landmarks that you may pass or miss entirely on the way up include a water pool (465m), the edge of a field (625m), a hut (794m), a cement marker (856m), a fence into a small pepper plantation (943m and 963m as you enter and exit), and you are likely to meet the original Cilentung trail at around (1,021m) which in 2020 still had the remains of a collapsed and abandoned warung. From there, the pandan trees appear the most dominant plant species as you near the crater (1,065m) which yet again features sadly abandoned warungs.
For an account of the original trail, and of the way up to the summit from the crater, read our report from 2010 below. Note that although reaching the summit is still possible, the lack of visitors now means it is likely to be more overgrown and therefore require more time. To be on the safe side, allow 3 hours for Citinggul to the crater, 2 hours for a return trip from the crater to the summit, and 2 hours back down to Citinggul.
The trail starts north of the mountain in Cilentung, 20km beyond Pandeglang on the narrow road leading down to the west coast of Java at Labuan. On the main road, there is a large, modern sign (at 481m) for the Pulosari crater (kawah) and waterfall (curug) pointing the way down a very bumpy track. About one kilometer down this track is a warung (small shop) and the centre of the village of Cilentung. There are more signs for the crater and enough room for about 2 cars next to the warung (you may have to pay about Rp10,000 for parking).
You cannot miss the start of the trail (at 501m), which leads up beyond the village through plantation and there are many signs on the route itself. After less than an hour you should have reached the Curug Putri waterfall (at 750m) where you have to pay Rp4,500 per person at the hut. It is not the most impressive waterfall in Java by any means but certainly an interesting feature on the trail and a place to cool off. The path then leads steeply up to the right and after another 45 minutes you should be close to the impressive rocky crater area (at 1,065m). Beside the white rocks and often dense clouds of sulphur gases there is, once again, a small warung and this area is a very popular place for local students to camp at weekends.
Straight above the crater area is the summit itself, about 300m up at the top of the vegetated crater wall. You may be able to see the transmitter on top. The trail leads up to the right of the crater and there are some very steep drops to the west so take extra care here. Occasional stone markers and the inevitable litter mark the way. There are also monkeys in this area which you might see. After climbing steeply over tree roots the vegetation becomes less dense and you see over the valley to the lesser peak of Aseupan and Java’s west coastline. As you near the top, there is a great spot looking directly west to Labuan and the Sunda Straits from the south-western edge of the narrow summit plateau. In good visibility the Krakatau islands lie directly beyond the power station chimney at Labuan.
Another ten minutes on the trail and you should have reached the peak. The fairly low height of the vegetation means that there are good views in all directions. The summit is crowned with a transmitter and earthquake monitoring equipment. There are a few places where local students like to camp at weekends. At the north-eastern tip of the summit ridge, beyond the transmitter, is a good vantage point for Gunung Karang and an occasional source of water. After enjoying the great views head back down the same way. Fast walkers can be back in Cilentung in two hours. Not bad for a day hike out of Jakarta!
Gunung Aseupan (1,174m)
Gunung Aseupan is the third highest peak in this region and is also a worthwhile day out. It is a complex range with various peaks. The two highest peaks can be hiked from separate starting points. The ridge which is the eastern part of the range can be accessed from the south via Ulun Jaya at Pak Marsem’s warung (455m) or nearby Pandat. The highest point of this long ridge is around 1,098m (but 1,127m according to the Bakosurtanal map) but has no views. (Thanks to John Hargreaves for this information).
However, the true summit is further west and is accessed from the south-west at Desa Sikulan (280m). This peak is clearly seen as a shapely triangle from the villages and main road below and is 1,174m above sea level. The shape of the peak gives the mountain its name. The true summit can be reached via two different ridges, but the more direct one leads to an incredibly overgrown and dangerously steep section just below the summit. Best take the slightly more eastern one that is clear for the most part. A guide will probably be needed as there are numerous junctions on the lower slopes of the mountain. Ask in the village for Bang Handa.
Lower down, the mountain is covered in clove and durian trees and there are also some attractive rice paddies. Higher up, the trail leads along a narrow, slippery forest ridge. There are lots of thorny plants here and also a few leeches. Near the summit are some pitcher plants (the Javan Nepenthes gymnamphora, according to expert Alastair Robinson). The summit itself is a small grassy area with excellent views in clear conditions of lower peaks in the range plus the other Pandeglang mountains and the coastline near Labuan. There is also an ancient grave and a summit sign. Most fit hikers can reach the top in 4-5 hours and be back down in 3-4, meaning this is possible as a daytrip from Jakarta if you set off before light.
Whereas in previous years nearby Pulosari saw many, many visitors every weekend, Gunung Aseupan is still not famous and only sees a handful of hikers each year (in 2020) though this may change in the future.

- Getting there: From Jakarta, take the toll road towards Merak, exit at the Pandeglang turn-off and turn right several kilometres beyond the town. For public transport, there are plenty of buses calling at Serang from where you can take an angkot to Pandeglang and then an ojek or further angkot onward to the starting point.

Origins and Meaning
(unclear) Pulo usually means “an island” but it also appears in several place names in Java (e.g. around Krawang) that are quite far from the sea. So it is possible that pulo also means something like “an outcrop”, “a prominence”, “something that rises from flat surroundings whether from the sea or from the land” or “an enclosed place”. It is also possible that pulo is a corruption of pala or pahala (pronounced /polo/ in Javanese) = “divinely bestowed reward for good deeds” or “the fruit of one’s deeds”, or simply “fruit”. Pulosari, then, might mean “the essence of divine reward” i.e. harking back to a time when people believed in karmic reward for good deeds, and mountains were venerated as the abode of deities and the source of good things.
