How to get there:
The trailhead (note that the one described by earlier climbers are not in use anymore) is located in the small village Nagalingga, at about 1470 meter of elevation, location N2.91956, E98.49024. It takes about 5 hours (depending on traffic) to drive there from the airport in Medan. For help and support contact Froden Nagalingga, whatsapp: +6285333632525.
Route description:
The first 2.5 kilometer follows farm roads. If available, one could get a motorbike ride. (This would make the hike 5 kilometer shorter, given that a return ride could also be arranged.) Next, the trail starts uphill from near a water channel. It soon becomes very nice as it very gently climbs among tall trees, however this will change higher up.
The route pretty much follows a ridge, west, then north to gain the east summit of the peak. There are steepish passages with roots to climb. Fairly common in Indonesia, it does require the use of hands here and there, I have given it a rating of (YDS) class 2+. (Class "tree climbing".) In October, after rain, the trail also gets increasingly more muddy, it is hard to avoid sinking in and getting wet. From the east summit, the trail continues (still muddy) about 0.7 kilometer across to the west summit< that has a proper summit marker. The route from Nagalingga village to the summit is 9.3 kilometer with a total vertical gain slightly more than 1000 meter.
Note that another trail (that has been closed!) ascends the east ridge and merges in on the east summit. Note how your route enters in order to avoid descending the "wrong ridge".
A track can be found on Peakbagger.
Comments:
I came to Medan from Banda Aceh, my car came about 30 minutes late, but by 1800 we were on the road heading for Nagalingga. More traffic and a few delays, but we did finally arrive shortly before 2300. With a start at 0500 the next morning, it would be a short night. I stayed in Froden's house, accommodation on the floor in a pretty big room'. There were more people sleeping there, with very noisy trucks running by (all night) right outside. I was happy having my inflatable air mattress, but sleep quality was definitely below average.
We started at 0500 as agreed. It turned out that Froden also had Chika come along, a friendly young woman, age 25. She has previously helped Froden with her English when communicating with me.
We reached the trailhead after about 35 minutes, then soon walked on the very nice initial part of this trail. Daylight arrived and the torchlight could go into the backpack. Soon, the trail turned into what is often the case in this part of the world, a steepish muddy climb on tree roots. We followed a ridge, at times quite well defined. A few local saddles were crossed and as the trail turned more north, the final ascent on the south ridge of the east summit was "root-free". We passed a concrete marker, it was clearly not on the highest point. The high point was among trees close to an open clearing. The time was already 0930, 4:30 to here showing that this was a "slow trail" for me. I continued after a brief stop, to tackle the remaining 700 meter traversing to the west summit. This section was again very muddy, if not wet already one would easily get wet here.
I arrived on the west summit at 0950, another break. I sat down and inspected my shoes, not a pretty sight. We waited for Chika, but she had decided to turn back about half way across. Froden went to look for her, before he returned, I decided to start back, the time was roughly 1020. I met him as he returned to the summit to retrieve his pack. I thought that we would perhaps join for a common break at the east summit.
The weather was just great, not a drop of rain, rather sunshine. I reflected on my luck so far. No rain on the peak 2 days ago. Continuous rain all of yesterday. There were a few places while descending from the west summit, that had views. I could see north to the nicely shaped Sinabung, only 7 meter lower. Also, more east to the slightly lower east summit. Finally, just right (south) of the east summit, the impressive crater lake Toba. This lake, with a large island in its middle is 3 times bigger than the largest lake in Norway.
Arriving at the East summit, no Chika. I therefore continued, but now managed to pick the wrong exit trail. Thus, I begun walking towards the east ridge. I realized my mistake after about 300 meter and turned back. By now, obviously, Froden would most likely have passed, expecting to catch up with me. Instead, he would catch Chika and likely be surprised. To help clearify matters, I sent him a text message explaining that I was behind, while still having mobile service high on the south ridge. Good views from here to Sinabung only 7 meter lower. Also, across to the east summit
I continued descending, careful not to make any slip or other mistake. It was not clear to me when Froden would have mobile service and see my message. This had indeed happened, they were waiting for me below most of the steepish sections. We continued down the nicer part of the route and finally got back to Nagalingga at 1520, total trip time 10:20.
Shortly after returning, Froden came back with a cold Bintang! What a nice surprise, most of Indonesia is muslim and alcohol is normally not available. Nagalingga, however is a catholic village, how lucky! Three hours after returning, a very violent rain started. We (my driver, Chika aand FRoden) joined for a nice local dinner at a nearby restaurant. Self serve style. After the meal you go to the cashier and tell her all you have taken, she then computes the charge. I appreciate that such schemes still exist in many locations, people trust each other and pay what should be paid.
